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.

Mengapa ukurannya harus sama persis? Tapi frekuensinya tidak tepat

How to change frequency

Hello! Thanks for the video, really interesting. I have a question, you mentioned that the surface is reflective but based on the radiation diagram, approximately the same amount of power that goes through the estructure is reflected (you have two lobes instead of one), why is that happening?

How can i calculate the inset for my antana?

Thanks!!

Sir, my s11 parameter is not crossing 10dB. what should I do?

sir, can you please suggest a method to extrude a ground plane to a non_planar gaussian surface?

Hello sir. Sir, can you please suggest if there is some method for connecting two non-planar gaussian surfaces in cst ?

Not sure if this will help someone. But I couldn't get the simulations to run using the R2024a version of MATLAB and the CST Studio Suite 2023 - [Learning Edition]. I kept encountering errors whenever any function was executed. I was able to bypass the problems by installing the same version of MATLAB as used in the video (MATAB R2016a - academic use) and then running them with the ST Studio Suite 2023 - [Learning Edition] and I had no errors.

Sir, How we will calculate the result. S pareter , VSWR ? It's showing error

I want to contact you. I am working on LUT based ring oscillator.

Greetings from Bangladesh! Thanks for the video (explained a key concept of RCS that I missed in the class lectures)

This video is 12 years old and it saved me today. Thanks a lot

Very useful videos. If possible, post any wearable antenna design with SAR analysis . Thank you so much

Can you provide with the cst file , I have also written you a email and also subscribe to your yt channel, I have also join the Facebook group

Hello. I get an error like this "The discrete port or lumped element Folder1:element1 was not found in the mesh. Please compare model and mesh view, and possibly use a different tetrahedral mesh generation method.". Do you know the solution? Thank you in advance.

Hello sir, can you help me design a linear to circular polarization antenna using metasurface?

very good , thank so much

THIS IS WHAT I NEEDED!

sir can you also make a video on how to calculate the input and output impedance of a common drain amplifier.

How can maximize the parameter list???

Great tutorial!

Hello. I get an error like this "The discrete port or lumped element Folder1:element1 was not found in the mesh. Please compare model and mesh view, and possibly use a different tetrahedral mesh generation method.". Do you know the solution?

One note: by default, when I add the HFSS solver, the solution type is "modal", this will cause issue when assigning excitations to the lumped port. This should be changed to "terminal". Otherwise, we can't find the same setting for the lumped port.

I want the design how can i get it

Dear Sir I am trying to design a Circularly Polarization reflective metasurface. I want to know, how to get the accurate circularly polarized reflection parameters when I try to illuminate the unit cell with a circularly polarized excitation wave. I set one Floquet port having two modes, 90 degree out of phase from each other. After simulation, I am able to plot the (FloquetPort1:1,FloquetPort1:1); S(FloquetPort1:2,FloquetPort1:2); S(FloquetPort1:2,FloquetPort1:1); S(FloquetPort1:1,FloquetPort1:2); But they both seem to represent the linear polarizations. How to get the circular polarization, like S(RHCP,LHCP);S(LHCP,LHCP). Is there any formula to calculate it? Thank you.

Thanku sooo much it's done after 3hrs...smjh nhi aa rha hasun ya roun😅

Hii.... I tried my best but I'm unable to create mirror patch antenna.... Please any one can help me? Pllllllzzzzzzzzzzz... Its more than 1hr i tried it 1000 times but mirror image is not created correctly

Thank you I found it helpful

Thank you for your sharing! I want to ask, if i use SMA female connector, how do i assign the wave port?

Hello Mr., your tutorial is very instructive. I have a question, how do you determine the different radius so that the structure resonates at the resonance frequency? I have a fused ring resonator and I'm having trouble finding the exact radius so that my structure resonates at my frequency (knowing that R=c/(4*pi*f0*sqrt(Epsi_eff))).
