Hi,guys
I am trying to correctly excite the TE21 mode in circular waveguide with HFSS. I set the number of modes as 5. The first two correspond to TE11 mode. And the third one corresponds to TM01 mode. The last two corrspond to TE21 mode. I used two perpendicular integration lines for TE11...
Hello, everyone
I am trying to draw the spiral phase plate in HFSS. I have worked on this for a long time, but I still can not create the structure. Does anyone know how to draw this? Could you give me some suggestions? Thanks a lot in advance!
Best regards!
Dear WimRFP
Thank you so much!
I simulate with HFSS 15. I set the ground plane as "Perfect E", and I also select the selection "Infinite Ground Plane", so I think it should be an infinite ground plane.
I have some new results. When I draw a rectangle at the boundary of the substrate and set it...
Dear WimRFP
Thanks for your reply, it helps me think. The radiation below the ground plane is from -50dB to -80dB, it is quite small. The ground plane has no thickness, I just draw a rectangle as the ground plane.
I tried the similar simulation with single patch. When I draw a circle at the...
Hi, everyone:
I am simulating a 4 patch array antenna. I set the GND as an infinite ground plane. But the problem is that there is still radiation pattern under the ground. What causes this result? can someone tell me? Thank you very much!
Best regards!
Hi everyone,
I am doing some simulations with the four patch antenna array. I used lumped port. The port is connected to the probe by transmission line. And the patch is fed by probe. I already did the matching work. However, when the length of the transmission line changes, the results of S...
