Thanks for the video. In my opinion, S11 < -30 dB should be considered excellent. It is very much possible to do in CST with fine tuning the T-line parameters.

Sir this journal paper send the link sir

Greetful

sir, if I placed metamaterial array over the patch return loss is giving good result but gain will be decreased, why?

Hi sir, i have simulated a cylindrical cavity resonator with a TE 011 mode at 8.5 GHz, when i placed a Dielectric resonator (DR) inside, the resonant frequency is increasing to 9 GHz, i am expecting to be lower than 8.5 GHz, do you know what had happens, sir?

choose brick,and press ESC to import parameters directly

Thank you.... can i know why S11 and S22 are not identical? and what port 1 and port 2 means? Also, i want to know how i can measure the far field pattern to obtain the phase shift of the mainlobe in the case of varactor based RIS?

How can I obtain a symmetry beamwidth in both planes?

How to obtain symmetric radiation pattern for a planar vivaldi?

How I can contact to you

Hi, how can we define a differential port feeding if the two input ports are not on the same plane ? orthogonal for example ? thank you in advance !

Thank you for this video, I have a question regarding this. If we already have the set of equations to design a Microstrip antenna, why would we need a DNN to perform this task ? , Additionally given the fact that getting a particular dataset might be computationally intensive, could we use RL learning to design such antennas ? Thanks

Thanks for giving a wonderful explanation about Vivaldi antenna. I want to design a Vivaldi antenna for 800 MHz to 3 GHz. I have tried both in planar and metal Vivaldi structure. Not getting resonance at lower frequency is 800 MHz to 1 GHz. What modification need to be considered for tuning at low frequency.

Very beneficial 🎉

It was the most clear tutorial I have ever seen , Thank you

Hello Sir,what is the name of designing program at time12:49?

reflectarray

CST benefits from GPU acceleration (With QUADRO GPU) in the time domain, but all periodic materials are modeled in the frequency domain 😐

Great .. '-'

How to check electric field of CDRA in CST

We have to submit project In a week need your guidance sir

Hello sir, I have simulated theAntenna with all the parameters as mentioned but unable to calculate the S-Parameter, VSWR... It is perfectly validating but on Analysing it is continuously showing tumor intersect with fabro, same with fat layer and same with skin layer.

Thank you for this video, please tell how i can insert my e',e'',u',and u'' data to the CST for RCS?

This is great and informative❤

I designed the antenna just like you did, following the steps. However, I couldn't achieve the same results. My S11 is -35 dB, and I'm using CST 2024. Do you know why this happened? I appreciated your video. Thanks so much!

Thank you

Thank you

Is matlab code available for this

Great video with a sound explanation. Assuming the 4 ports of the VNA are to be calibrated, how do you achieve that with the same CAL KIT ?

Where the lambda is at the lowest or highest operating frequency?

Is it possible to have a plot of the field magnitude using a surface. Im studying the enhancement of the field between metal antenna arms. So i would like to have a 2D rectangle placed in between the arm giving me info on the amplitude of the field for a frequency sweep. I searched everywhere but couldn't find any solutions. Thanks

Please share the microstrip dimension calculation

hi! very nice tutorial.. i want to study an antenan over an infinite plane and find the impedance ?

do reply how to find power loss in cst for this antenna

Can anyone please tell me how to find power loss by antenna??

I don't know why I can't click the Floquet port. Someone help me, please.

Hello,Why in the Begining you did not take periodique structures instead of Planar antennas?

Thank you for such a wonderful explanation.......can you please make a video on how to calculate dimensions for a particular frequency?

How to simulate diode using S2P file for ON OFF purpose in CST using Schematic

very interesting video! Can you share the paper about the permittivity values of the skin etc especially the tumor? Thanks in advance

Thank you for informative tutorial!

Sir, How to define the ring dimensions?

It is not working for [Learning edition]

Thanks for the nice tutorial🤍

For the unit cell gain is showing -200dB, am I wrong in the design please?

how to maximum transmission in cst unit cell design and array full simulation

can it be done in hfss,,,,put a video of that.....how the dimensions of ring and substrate are decided. please help me out

Hi sir, you explain every very clearly and efficiently but one thing I don't know that how can we calculate the parameters or dimension for our desire AMC.

Thank you for this wonderful tutorial on load-pull for power amplifiers. you used PSS analysis, what about hb? and you have done it for single-ended output, what about differential output. If it is possible do you have personal contact, I want to discuss some issues related to this Topic in RF amplifiers. Waiting for your kind response. 🌹🌹🌹 best regards.
