So, I would like to feed my Horn antenna with coax in my HFSS simulation. But when I do this, the S11 goes below -5.00 dB. My waveguide Cut-off frequency is 21GHz, and my operating range is from 26.5 to 40GHz.


I tried my Coax model only with the waveguide. That time, I got S21 at -1.5dB, which is good. But when I connect it with Horn, why am I getting this kind of response? The Coax impedance is 50 ohms!
