Hi, everyone!
I am simulating an on-chip 77GHz Artificial magnetic conductor(AMC) structure. When I simulated the AMC unit cell in HFSS, I got the rigth in-phase frequency but the return loss S11 is around -10dB which means only few waves are reflected by AMC. Do you have any idea to increase the S11 to near 0dB?
This is my AMC unit cell simulation model.
Simulation results. Reflection phase is at 77G. But S11 is just -10dB
I found this from a paper. We use the same AMC shape but his S11 is around -2dB
Can anyone helps me? Thanks in advance!
