Sorry for the bad quality, I was kinda tired.
Patch Antenna Basics (Part 1) - Design

In this video, I'll describe the basic steps needed to design a patch antenna that resonates at 6 GHz. I explain the foundations of the equations involved, as well as how the actual design is derived. Additionally, I cover the types of feed structures, design prerequisites, and more. Chapters: 00:00 - Introduction 00:46 - Types of Patches 01:58 - Design Prerequisites 03:43 - Deriving Width 04:5...
Where did you get the PCell scripts etc ?
the gm seems so exceedingly small, using the lvt transistor I was able to get around 0.4mS. e-12 doesn't make sense..
Yeah I noticed that too originally. I think I ended up updating Ngspice and got more accurate results
hey how do i check where my .lib.spice is?? please help
Thanks
Thank you for making tutorials about open source eda
Bro how can i plot various mosfet parameters like gm, cgs for better understanding like we do in cadence
Thank you so much for the great explanation! I'm new to antenna design, and i've some questions, How did you figure out which parameter is responsible for the optimization of the S11 parameter? i mean i know the theory about the length and the width of the antenna and equations and so on , but sometimes i find some difficulties while trying to optimize, i sometimes make it even worst, especially when i don't know the range that i should set for sweeping.
I love it 😍
Great tutorial, thanks 👍🏻👍🏻👍🏻
Excellent tutorial 💯 Where is the following video you mentioned?
Ya i cant find the next video for layout?
Hi, could you make a how to install xschem with all needed tools? I'm on my third try :(
Sure! It’s definitely a tedious process. What I’m using in this video is the sky130 docker container, it bundles everything into a container and is very easy to install. github.com/efabless/foss-asic-tools
Why do we only get one gm, gds, ...etc ? Shouldn't these parameters vary with Vgs ?
It gives you parameter values of gm, gds, etc. of the last voltage in the sweep. In this case Vgs was swept up to 3V, so the gm and gds are representative of Vgs = 3.0 V

Hi, How can i configure skywater in klayout?
Try following the instructions here: github.com/mabrains/sky130_klayout_pdk
@@ryanwans391 Doesn't work.
@@pentachronic yeah I havnt really used the PDK in a while so not sure about the best way to configure it currently. Try joining the Sky130/efablass Slack channel and asking there
Can anyone figured out.. how to use sky130 technology with klayout? Any video...😭😭
very cool!
Thanks very much - a really useful video that helped to get me started with Xschem. One question though, when you display all the attributes of the nfet after the first simulation, the dimensions show 5 fingers and a width of 2 microns - different to the schematic (I was comparing my gm and Vt outputs to yours and noticed the difference). Do you have another nfet on the schematic we can't see?
Ah yes! I didn’t catch this at first. I had originally set up a different test structure to the side, which is why my values did not change after a second simulation and the sizing looks off
really great explanation ... is the same formulas are used for rectangular patch??
Yes! The example in the video is actually a rectangular patch, so those are the correct equations
can you tell me please , the equtions in which reference ??....i did not find them in balanis 4th edition
@@AmirKhan-qh6yi In this video, I reference both Balanis' literature and Modern Antenna Design by Milligan.
