April 2024 Wrapup

The way this month has ended has coloured most of everything else happening within the month, none of which is stuff I consider meaningful content for the blog in general. Suffice to say this is a month in which I was trying to save money and do my best and by the end of the month I am extremely frazzled and uncertain as to how I’m doing what I’m doing. But you didn’t come here for that, you came here for posts! Posts about Spiderman!

Alright let’s dive on into this. What are the Game Pile articles this month?

Examining Gender and Capitalism in Braid. This video got me a comment I liked a lot where a commenter noted that being good at making puzzles doesn’t make you any good at criticising humans’ reactions to puzzles.

Sheriff of Nottingham, a dramatic tension and bluffing game, where players have to construct a language, then lie in it, all with a dash of political manipulation in the form of bribes. A great game in the ‘Anxiety Engine’ model that I like but never am likely to own.

Planetfall and Bioshock Infinite, a long form essay video where I both recapped the basic experience of Bioshock Infinite and brought into contrast the idea that videogames’ ability to affect their audience is directly in contrast to different aesthetic forms.

Gazillionaire, a truly awful looking game that, hilariously, just after I wrote this article I finally played to a victory. Know what happens when you beat the game? The game keeps going and just moves the goal post further.

And then the Story Pile articles?

Hazbin Hotel, a series you should steal about a particularly pre-modern Christian vision of Hell expressed through gnostic mysterio and also the story of a bunch of shockingly hot endearing monster weirdoes.

You Were Never Really Here, which is part of an ongoing series of Positronic Collection movies. This was chosen specifically to mesh with the theme of me, as a person, and it’s kinda eerie how good a job it does at that.

16 Bit Sensation: Another Layer, which is an anime that you might think of as ‘fun’ and ‘good’ and which made me so mad I specifically set aside the time to kick it in the teeth into my April articles.

Oshi no Ko, a series I like just enough to complain about it a bunch. I mean I really like it, and really like complaining about it.

Lords and Ladies, one of the many books I consider one of the best Discworld books. This one’s about elves!

But there’s more! I wrote about a brilliant idiot, in the form of the transformer Wheeljack, and I wrote about my demon boy OC big brother figure, Bael. I wrote about a Magic: The Gathering deck I like and technology in the game I dislike that we’re getting even though I dislike it. I also spent some time reflecting on my current WIP game designs, which I found a lot of fun and want to do more of.

I talk to you a little bit. I talked to you in terms of what I think of you as an audience, I talk to you about creating tension in your writing, and I talked about the way I treat you, and how your time is a gift. I reflected on what it means to be a part of my audience, and whether or not there are things about you I can control. I also encouraged you to make things and show them to me, as a present to me.

There was some world-building talk; I talked about the way planes can be seen and treated as distinct parts of the world, with Planar Lenses, and I also explained a setting element in Cobrin’Seil, a favourite place where the wizards and sorcerers train together but also learn how to swing a hammer. That place, The Laewaes Dramaturgist, also served to talk about the ways that people in universe, in general, discuss the idea of types of spellcasters. While I was on the D&D thread and organisational systems, I dug into the 3rd edition magic item system. While talking about my personal fascinations in D&D, then, I also talked about the druid, and Why Is Druid?

This turning of the years in April, again, does make me think about things I was told about how my life would go. One of the most miserable considerations there was the way I was told that my sex life was going to go, and what that meant and what I should be expecting, all told while we should definitely, definitely not have opinions or expectations for sex. This was told through a metaphor of a jellybean jar.

I noticed that the logo for Hazbin Hotel, the key, looks a bit like the Sonic the Hedgehog winged ring logo and that’s what gave rise to this. Behold! A drawing of two characters with one looking happily at her idiot. You can get it as a sticker, or coasters, or a t-shirt. For example.

I don’t like how much work I got done this month. Obviously, I fear that if I go back and look at all the other posts I made this past year that may be the case. But in the PhD, last month featured a dedicated chunk of work on my literature review, and this month should be the completion of the draft of the methodology. We’re now at the point of getting things onto the page, and as I write this �� on the 27th – my birthday has proven to be an impediment for that. Like, turns out that people want to see you on your birthday.

At the late point in the month I devised a new idea for something cool and complicated (and more about that on the Patreon). I have a want to do something cool with a few different systems – a new game mechanical idea, and a push for a kind of video that’s a little easier to make than most.

May has five Fridays in it, and they’re set up so there are going to be three main videos in it, so look forward to that!

Isekai Trucking Inc.

The Fabulous True Story of Isekai Trucking Inc., Kun Collections, 2020

No relationship to Fridge Hauler, one of my previous reviews.

For those who don't get the reference: "Isekai", sometimes called "portal fantasy", is where someone from our wold ends up in another one. They often get there in a way that leaves it ambiguous or heavily implied that they died in the process. The most common way this happens is when they're crossing the road and there's a truck headed right for them, and they wake up in this other world. Which is probably not a last-moments hallucination but maybe... So yeah. Isekai Trucking.

Villains have overrun your world. They have something that can stop your every efforts, thwart all your magic. Your world needs heroes. It's your job to go out and get them. As many as possible. Only the magical energy released by near-death experience can trigger planar travel, so here you are, causing as much near-death as you can as quickly as possible. With a giant truck.

You do need to balance hitting people with your truck (which thankfully leaves no evidence) with actually getting caught. Getting caught is likely to put you in a near-death experience, which sends you back to your world. That's no good. Getting thrown in our prisons with their iron bars and steel manacles, that's no good either. You need to be sneaky. And clever. And probably befriend some humans who can help cover for you. And then steal a truck and hit people with it.

This is complicated by the fact that you play "fey" monsters. The system doesn't do a whole lot to support that. It's assumed that you're wearing the traditional "Benjamin Grimm in a trenchcoat" level of disguise, that you have no special strength or powers beyond mild cartoon wackiness and the kind of extreme resiliency that comes with "Heal all damage every morning". It does make the art fun. A goblin made of pipe cleaners hanging off the side of a dump truck with a baseball bat. A crazed garbage can with eyes staring out, hands on the steering wheel. A giant fuzzball engulfing a screaming pedestrian. It's all black-and-white Palladium-level stuff, but that honestly fits pretty well.

Rules are a GURPS-inspired 3d6 roll-under, with the usual four stats, a handful of mostly psychological advantages/disadvantages, and maybe more skills than you need. There are only 20 of them, but I feel like Driving, Stealth, Menace, Explain, Wait Let Me Explain (a separate and amazing skill), and Cunning cover an awful lot of territory for this game. The game would benefit from some more modern design, and maybe even being transformed into a spinoff of Eat God.

Isekai Trucking was distributed in EPS format (why???). It was on Itch for a while, but in the process of moving it over to another distributor KunColl accidentally introduced a non-Unicode character string into the title and now they can't open the original any more. They've declared the original CC-BY 4.0. Version 1.02 is the latest one if you're lucky enough to find multiple versions.

Rigid-Flex PCB: Revolutionizing Electronics with Flexibility and Rigidity

In the ever-evolving landscape of electronics, innovation often comes in the form of new materials and designs that push the boundaries of what is possible. Rigid-Flex PCB (Printed Circuit Board) is a prime example of such innovation, seamlessly combining the benefits of rigidity and flexibility to meet the demands of modern electronic devices. This hybrid construction has transformed the way electronic components are integrated, offering designers greater flexibility and versatility.

Understanding Rigid-Flex PCB: At its core, a Rigid-Flex PCB is a combination of rigid and flexible circuitry within a single board. It consists of both rigid sections, typically made of FR-4 material, and flexible sections, composed of polyimide or similar flexible substrates. This unique construction allows the board to bend or fold without compromising the integrity of the circuitry.

Versatility in Design: One of the primary advantages of Rigid-Flex PCB is its versatility in design. Traditional rigid boards are limited by their fixed shape, whereas flexible circuits can conform to non-planar surfaces. Rigid-Flex PCBs bridge this gap, offering designers the freedom to create 3D configurations that were once challenging or impossible with separate rigid and flexible boards.

Space Efficiency and Weight Reduction: The integration of rigid and flexible sections in a single board leads to enhanced space efficiency. Instead of using connectors and cables to link separate rigid and flexible boards, Rigid-Flex PCBs eliminate these additional components, reducing the overall size and weight of the electronic device. This is particularly beneficial in applications where size and weight constraints are critical factors.

Reliability and Durability: Rigid-Flex PCBs offer improved reliability compared to assemblies using connectors and cables. The elimination of interconnects reduces the points of failure, minimizing the risk of signal degradation, electrical noise, and mechanical wear. The seamless integration of rigid and flexible sections ensures durability, making Rigid-Flex PCBs suitable for applications subjected to repeated bending or flexing.

Complex Circuitry Integration: The combination of rigid and flexible sections facilitates the integration of complex circuitry within a compact space. Designers can strategically place rigid areas for components requiring stability and flexibility in sections that demand adaptability. This capability is especially advantageous in densely populated electronic devices where space optimization is critical.

Applications in Various Industries: Rigid-Flex PCB technology has found applications in a diverse range of industries. From aerospace and automotive to medical devices and consumer electronics, the adaptability of Rigid-Flex PCBs makes them suitable for numerous applications. In the automotive sector, for instance, Rigid-Flex PCBs are employed in airbag systems, control modules, and instrument clusters, benefiting from the space-saving and reliability features.

Challenges and Considerations: While Rigid-Flex PCBs offer significant advantages, their design and manufacturing present unique challenges. Designers must carefully consider factors such as material compatibility, bend radius, and layer stackup. Collaboration between electrical and mechanical engineers is crucial to ensure that the final design meets both electrical and mechanical requirements.

Conclusion: In conclusion, Rigid-Flex PCB technology represents a paradigm shift in the world of electronic design and manufacturing. Its ability to seamlessly blend rigidity and flexibility opens up new possibilities for compact, lightweight, and reliable electronic devices. As technology continues to advance, Rigid-Flex PCBs will likely play an increasingly pivotal role in shaping the future of electronic innovations, offering a harmonious blend of form and function in the realm of printed circuit boards.

With just a little electricity, MIT researchers boost common catalytic reactions

New Post has been published on https://thedigitalinsider.com/with-just-a-little-electricity-mit-researchers-boost-common-catalytic-reactions/

With just a little electricity, MIT researchers boost common catalytic reactions

A simple technique that uses small amounts of energy could boost the efficiency of some key chemical processing reactions, by up to a factor of 100,000, MIT researchers report. These reactions are at the heart of petrochemical processing, pharmaceutical manufacturing, and many other industrial chemical processes.

The surprising findings are reported today in the journal Science, in a paper by MIT graduate student Karl Westendorff, professors Yogesh Surendranath and Yuriy Roman-Leshkov, and two others.

“The results are really striking,” says Surendranath, a professor of chemistry and chemical engineering. Rate increases of that magnitude have been seen before but in a different class of catalytic reactions known as redox half-reactions, which involve the gain or loss of an electron. The dramatically increased rates reported in the new study “have never been observed for reactions that don’t involve oxidation or reduction,” he says.

The non-redox chemical reactions studied by the MIT team are catalyzed by acids. “If you’re a first-year chemistry student, probably the first type of catalyst you learn about is an acid catalyst,” Surendranath says. There are many hundreds of such acid-catalyzed reactions, “and they’re super important in everything from processing petrochemical feedstocks to making commodity chemicals to doing transformations in pharmaceutical products. The list goes on and on.”

“These reactions are key to making many products we use daily,” adds Roman-Leshkov, a professor of chemical engineering and chemistry.

But the people who study redox half-reactions, also known as electrochemical reactions, are part of an entirely different research community than those studying non-redox chemical reactions, known as thermochemical reactions. As a result, even though the technique used in the new study, which involves applying a small external voltage, was well-known in the electrochemical research community, it had not been systematically applied to acid-catalyzed thermochemical reactions.

People working on thermochemical catalysis, Surendranath says, “usually don’t consider” the role of the electrochemical potential at the catalyst surface, “and they often don’t have good ways of measuring it. And what this study tells us is that relatively small changes, on the order of a few hundred millivolts, can have huge impacts — orders of magnitude changes in the rates of catalyzed reactions at those surfaces.”

“This overlooked parameter of surface potential is something we should pay a lot of attention to because it can have a really, really outsized effect,” he says. “It changes the paradigm of how we think about catalysis.”

Chemists traditionally think about surface catalysis based on the chemical binding energy of molecules to active sites on the surface, which influences the amount of energy needed for the reaction, he says. But the new findings show that the electrostatic environment is “equally important in defining the rate of the reaction.”

The team has already filed a provisional patent application on parts of the process and is working on ways to apply the findings to specific chemical processes. Westendorff says their findings suggest that “we should design and develop different types of reactors to take advantage of this sort of strategy. And we’re working right now on scaling up these systems.”

While their experiments so far were done with a two-dimensional planar electrode, most industrial reactions are run in three-dimensional vessels filled with powders. Catalysts are distributed through those powders, providing a lot more surface area for the reactions to take place. “We’re looking at how catalysis is currently done in industry and how we can design systems that take advantage of the already existing infrastructure,” Westendorff says.

Surendranath adds that these new findings “raise tantalizing possibilities: Is this a more general phenomenon? Does electrochemical potential play a key role in other reaction classes as well? In our mind, this reshapes how we think about designing catalysts and promoting their reactivity.”

Roman-Leshkov adds that “traditionally people who work in thermochemical catalysis would not associate these reactions with electrochemical processes at all. However, introducing this perspective to the community will redefine how we can integrate electrochemical characteristics into thermochemical catalysis. It will have a big impact on the community in general.”

While there has typically been little interaction between electrochemical and thermochemical catalysis researchers, Surendranath says, “this study shows the community that there’s really a blurring of the line between the two, and that there is a huge opportunity in cross-fertilization between these two communities.”

Westerndorff adds that to make it work, “you have to design a system that’s pretty unconventional to either community to isolate this effect.” And that helps explain why such a dramatic effect had never been seen before. He notes that even their paper’s editor asked them why this effect hadn’t been reported before. The answer has to do with “how disparate those two ideologies were before this,” he says. “It’s not just that people don’t really talk to each other. There are deep methodological differences between how the two communities conduct experiments. And this work is really, we think, a great step toward bridging the two.”

In practice, the findings could lead to far more efficient production of a wide variety of chemical materials, the team says. “You get orders of magnitude changes in rate with very little energy input,” Surendranath says. “That’s what’s amazing about it.”

The findings, he says, “build a more holistic picture of how catalytic reactions at interfaces work, irrespective of whether you’re going to bin them into the category of electrochemical reactions or thermochemical reactions.” He adds that “it’s rare that you find something that could really revise our foundational understanding of surface catalytic reactions in general. We’re very excited.”

“This research is of the highest quality,” says Costas Vayenas, a professor of engineering at the university of Patras, in Greece, who was not associated with the study. The work “is very promising for practical applications, particularly since it extends previous related work in redox catalytic systems,” he says.

The team included MIT postdoc Max Hulsey PhD ’22 and graduate student Thejas Wesley PhD ’23, and was supported by the Air Force Office of Scientific Research and the U.S. Department of Energy Basic Energy Sciences.

How do you Define it Microstrip antenna ?

Guide of microstrip antenna 

A microstrip antenna is used to process ultra-high frequency signals. It is often used as a satellite radio or cell phone receiver or is mounted on a spacecraft or aircraft. This type of antenna has the benefit that it costs little to make but the drawback is that it has limited bandwidth.

An antenna is basically a device designed to transmit or receive electromagnetic waves by the students of best engineering colleges in Jaipur. It is used in radio equipment to transform radio waves into electrical currents or electrical currents into radio waves. The only difference between a transmitting antenna and a receiving antenna is the direction in which the signal is traveling. A microstrip antenna is also used to transmit or receive signals in the ultra-high frequency spectrum. These waves have the frequencies between 300 MHz and 3000 MHz (3GHz).

The most common type of microstrip antenna is considered as microstrip patch antenna. It is made by engraving the antenna pattern into metal trace. It is bonded to a layer of insulating material like plastic, glass, certain ceramics, or certain types of crystal, then the insulating layer, known as the dielectric substrate, is bonded to a layer of metal. You cannot create this type of antenna without a dielectric substrate.

Benefits Of Microstrip Patch Antenna

A microstrip antenna is a low-cost and versatile antenna that can be manufactured easily and produces high-quality signals. Its benefits include lightweight, low manufacturing cost, and directivity.

Low cost

Patch antennas are highly versatile and low-cost in terms of manufacturing. They are low in weight, small in size, and offer low radiation power to the students of top engineering colleges in Jaipur. They can operate in dual and triple frequencies and are perfect for various applications. The low-profile design of these antennas allows easy incorporation into a circuit board. Also, they are easy to mount on a rigid surface.

Typically, Microstrip antennas are very thin. Therefore, people often print them on a single dielectric substrate. Patch antennas includes a layer of dielectric material. Each layer has 60 RF MEMS varactor elements.

Easy to manufacture

Microstrip antennas are simple and inexpensive that is very flexible. The planar structure allows enable them to conform to surfaces without losing their mechanical strength, even when mounted on rigid materials. Such antennas are helpful in various applications, and their low profile makes them easy to integrate into a device. Also, they are inexpensive to produce and can print onto a circuit board.

The microstrip antenna consists of many different materials. A common material is an aluminum, which is incredibly easy to work with. You can cut and form the metal in a simple machine. The aluminum microstrip can be easily assembled and the aluminum substrate makes it lightweight and durable.

Lightweight

Microstrip patch are popular as low-profile and lightweight antennas that operate at a wide frequency range. Additionally, they are easy to manufacture and integrate. These features help students of best private engineering college in Jaipur to make them attractive candidates for use in wireless communication systems. Patch antennas are available in different shapes and uses a series of strips in an array. Some common shapes include a circular ring, a square, or an elliptical shape.

Small distances

Patch antennas are categorized into a conductive strip and a dielectric substrate. This method is useful for short distances, where you fabricate high-frequency signals without sacrificing efficiency. Here, the antennas narrow bandwidth makes them unsuitable for use in large area networks.

Patch antennas are a modern invention that allows easy integration of antenna and driving circuitry on a single circuit board or semiconductor chip. It maintains high dimensional accuracy, which was previously impossible with traditional fabrication methods.

Types Of Microstrip Antennas

Custom antenna PCB

Microstrip patch includes several types of materials. The conducting patch can be RT-Duroid, FR-4, foam, Nylon fabric, etc. Also, they consist of dielectric substrates with different dielectric constants. They are helpful for fabrication, and it is usually thick. Each type uses a different feeding technique to feed the patch to the substrate by the students of best BTech college in Jaipur.

Parasitic patch

A parasitic patch antenna is a stacked microstrip antenna that has a radiating part composed of nine rectangular metal patches arranged basically in three rows and three columns. Due to this, the regular concept makes the antenna’s radiation pattern uniform and can cover a wide bandwidth.

The antenna has a central patch 24 that combines several smaller patches, or “parasitic patches,” which further connects each other at the center frequency f. The central patch 24 has a slot 40 and two equal-sized notches, 44 a and b, each 125 mm wide. With the increase in the parasitic patches, the antenna’s profile also got increased.

Dielectric chip

The dielectric loading in a micro strip antenna that affects the radiation pattern and impedance bandwidth. The higher the dielectric constant, the smaller the bandwidth of the antenna will become. Additionally, increasing the substrate’s relative permittivity increases the antenna’s Q factor. Due to this, the radiation pattern of a rectangular micro strip antenna is an array of slots. The highest directivity only occurs when the dielectric of the substrate is air. Therefore, the relative permittivity of the dielectric expands as the substrate becomes more dielectric.

Micro strip

A micro strip antenna is an important and popular type of internal antenna. They are helpful for microwave frequencies and consist thin strips of metal, and are useful in many applications. These strips are made of gold or silver. This type of antenna is also helpful in microwave ovens. A micro strip antenna is useful in different applications where a longer, stronger antenna is needed.

Nanoparticles self-assemble to harvest solar energy

The technology transforms sunlight into thermal energy, but it’s challenging to suppress energy dissipation while maintaining high absorption. Existing solar energy harvesters that rely on micro- or nanoengineering don’t have sufficient scalability and flexibility, and will require a novel strategy for high-performance solar light capture while simultaneously simplifying fabrication and reducing costs. In APL Photonics, from AIP Publishing, researchers from Harbin University, Zhejiang University, Changchun Institute of Optics, and the National University of Singapore designed a solar harvester with enhanced energy conversion capabilities. The device employs a quasiperiodic nanoscale pattern — meaning most of it is an alternating and consistent pattern, while the remaining portion contains random defects (unlike a nanofabricated structure) that do not affect its performance. In fact, loosening the strict requirements on the periodicity of the structure significantly increases the device’s scalability. The fabrication process makes use of self-assembling nanoparticles, which form an organized material structure based on their interactions with nearby particles without any external instructions. Thermal energy harvested by the device can be transformed to electricity using thermoelectric materials. “Solar energy is transferred as an electromagnetic wave within a broad frequency range,” said author Ying Li of Zhejiang University. “A good solar-thermal harvester should be able to absorb the wave and get hot, thereby converting solar energy into thermal energy. The process requires a high absorbance (100% is perfect), and a solar harvester should also suppress its thermal radiation to preserve the thermal energy, which requires a low thermal emissivity (zero means no radiation).” To achieve these goals, a harvester is usually a system with a periodic nanophotonic structure. But the flexibility and scalability of these modules can be limited due to the rigidity of the pattern and high fabrication costs. “Unlike previous strategies, our quasiperiodic nanophotonic structure is self-assembled by iron oxide (Fe3O4) nanoparticles, rather than cumbersome and costly nanofabrication,” said Li. Their quasiperiodic nanophotonic structure achieves high absorbance (greater than 94%), suppressed thermal emissivity (less than 0.2), and under natural solar illumination, the absorber features a fast and significant temperature rise (greater than 80 degrees Celsius). Based on the absorber, the team built a flexible planar solar thermoelectric harvester, which reached a significant sustaining voltage of over 20 millivolts per square centimeter. They expect it to power 20 light-emitting diodes per square meter of solar irradiation. This strategy can serve low-power density applications for more flexible and scalable engineering of solar energy harvesting. “We hope our quasiperiodic nanophotonic structure will inspire other work,” said Li. “This highly versatile structure and our fundamental research can be used to explore the upper limit of solar energy harvesting, such as flexible scalable solar thermoelectric generators, which can serve as an assistant solar harvesting component to increase the total efficiency of photovoltaic architectures.”

A Practical Guide to the Design of Microstrip Antenna Arrays - Arya College

A microstrip antenna is used to process ultra-high frequency signals. It is often used as a satellite radio or cell phone receiver or is mounted on a spacecraft or aircraft. This type of antenna has the benefit that it costs little to make but the drawback is that it has limited bandwidth.

An antenna is basically a device designed to transmit or receive electromagnetic waves by the students of best engineering colleges in Jaipur. It is used in radio equipment to transform radio waves into electrical currents or electrical currents into radio waves. The only difference between a transmitting antenna and a receiving antenna is the direction in which the signal is traveling. A microstrip antenna is also used to transmit or receive signals in the ultra-high frequency spectrum. These waves have the frequencies between 300 MHz and 3000 MHz (3GHz).

The most common type of microstrip antenna is considered as microstrip patch antenna. It is made by engraving the antenna pattern into metal trace. It is bonded to a layer of insulating material like plastic, glass, certain ceramics, or certain types of crystal, then the insulating layer, known as the dielectric substrate, is bonded to a layer of metal. You cannot create this type of antenna without a dielectric substrate.

Benefits Of Microstrip Patch Antenna

A microstrip antenna is a low-cost and versatile antenna that can be manufactured easily and produces high-quality signals. Its benefits include lightweight, low manufacturing cost, and directivity.

Low cost

Patch antennas are highly versatile and low-cost in terms of manufacturing. They are low in weight, small in size, and offer low radiation power to the students of top engineering colleges in Jaipur. They can operate in dual and triple frequencies and are perfect for various applications. The low-profile design of these antennas allows easy incorporation into a circuit board. Also, they are easy to mount on a rigid surface.

Typically, Microstrip antennas are very thin. Therefore, people often print them on a single dielectric substrate. Patch antennas includes a layer of dielectric material. Each layer has 60 RF MEMS varactor elements.

Easy to manufacture

Microstrip antennas are simple and inexpensive that is very flexible. The planar structure allows enable them to conform to surfaces without losing their mechanical strength, even when mounted on rigid materials. Such antennas are helpful in various applications, and their low profile makes them easy to integrate into a device. Also, they are inexpensive to produce and can print onto a circuit board.

The microstrip antenna consists of many different materials. A common material is an aluminum, which is incredibly easy to work with. You can cut and form the metal in a simple machine. The aluminum microstrip can be easily assembled and the aluminum substrate makes it lightweight and durable.

Lightweight

Microstrip patch are popular as low-profile and lightweight antennas that operate at a wide frequency range. Additionally, they are easy to manufacture and integrate. These features help students of private engineering colleges in Jaipur to make them attractive candidates for use in wireless communication systems. Patch antennas are available in different shapes and uses a series of strips in an array. Some common shapes include a circular ring, a square, or an elliptical shape.

Small distances

Patch antennas are categorized into a conductive strip and a dielectric substrate. This method is useful for short distances, where you fabricate high-frequency signals without sacrificing efficiency. Here, the antennas narrow bandwidth makes them unsuitable for use in large area networks.

Patch antennas are a modern invention that allows easy integration of antenna and driving circuitry on a single circuit board or semiconductor chip. It maintains high dimensional accuracy, which was previously impossible with traditional fabrication methods.

Types Of Microstrip Antennas

Custom antenna PCB

Microstrip patch includes several types of materials. The conducting patch can be RT-Duroid, FR-4, foam, Nylon fabric, etc. Also, they consist of dielectric substrates with different dielectric constants. They are helpful for fabrication, and it is usually thick. Each type uses a different feeding technique to feed the patch to the substrate by the students of best BTech colleges in Jaipur.

Parasitic patch

A parasitic patch antenna is a stacked microstrip antenna that has a radiating part composed of nine rectangular metal patches arranged basically in three rows and three columns. Due to this, the regular concept makes the antenna’s radiation pattern uniform and can cover a wide bandwidth.

The antenna has a central patch 24 that combines several smaller patches, or “parasitic patches,” which further connects each other at the center frequency f. The central patch 24 has a slot 40 and two equal-sized notches, 44 a and b, each 125 mm wide. With the increase in the parasitic patches, the antenna’s profile also got increased.

Dielectric chip

The dielectric loading in a microstrip antenna that affects the radiation pattern and impedance bandwidth. The higher the dielectric constant, the smaller the bandwidth of the antenna will become. Additionally, increasing the substrate’s relative permittivity increases the antenna’s Q factor. Due to this, the radiation pattern of a rectangular microstrip antenna is an array of slots. The highest directivity only occurs when the dielectric of the substrate is air. Therefore, the relative permittivity of the dielectric expands as the substrate becomes more dielectric.

A microstrip antenna is an important and popular type of internal antenna. They are helpful for microwave frequencies and consist thin strips of metal, and are useful in many applications. These strips are made of gold or silver. This type of antenna is also helpful in microwave ovens. A microstrip antenna is useful in different applications where a longer, stronger antenna is needed.

            Sphericity is an assumed characteristic of data analyzed in repeated measures analysis of variance (ANOVA). Sphericity refers to the equality of variances of the differences between treatment conditions. Violations of the sphericity assumption do not invalidate a repeated measures ANOVA but do necessitate using corrected F ratios. If compound symmetry is met, sphericity assumption will also be met. Var(yij yik) = Var(yij) + Var(yik) 2Cov(yij;yik) = 2˙2 Y 2˙ 2 ˆ= 2˙ 2 e Nathaniel E. Helwig (U of Minnesota) Linear Mixed-Effects Regression Updated 04-Jan-2017 : Slide 18 First, to conveniently capture particle characteristics, this work established estimation functions of 3D shape parameters (elongation, flatness, sphericity, and convexity). Then, the present study proposed a novel stochastic algorithm for generating non-convex particles. (This algorithm successfully controls the above particle shape parameters.) Factor Analysis (FA) is an exploratory data analysis method used to search influential underlying factors or latent variables from a set of observed variables. It helps in data interpretations by reducing the number of variables. It extracts maximum common variance from all variables and puts them into a common score. Sphericity. This means that the population variances of all possible difference scores (com_1 - com_2, com_1 - com_3 and so on) are equal. Sphericity is tested with Mauchly's test which is always included in SPSS' repeated measures ANOVA output so we'll get to that later. 3. Quick Data Check Microscopy Image Analysis Software - Imaris - Oxford Instruments realignment involves (i) estimating the 6 parameters of an affine 'rigid-body' transformation that minimizes the [sum of squared] differences between each successive scan and a reference scan (usually the first or the average of all scans in the time series) and (ii) applying the transformation by re-sampling the data using tri-linear, sinc or … The assumption of sphericity can be likened to the assumption of homogeneity of variance (see your handout on exploring data): if you were to take each pair of treatment levels, and calculate the differences between each pair of scores, then it is necessary that these differences have equal variances (see Field, 2009). First, we need to tell SPSS what our between-participants variable is. To do this, SELECTthe Participant Race variable and move it across to the Between-Subjects Factor(s) box by CLICKINGon the blue arrow to the left of the box.
