Hi, I am working with an Coax to waveguide transition for Ka band with a 2.92mm end launcher, I have created the 3-D model in HFSS and also specified the required dimensions for the inner and outer cylinder for the coax . After simulation the the S-parameters are not what I am looking for. It should be -10 dB for the entire band as the waveguide is WR-28.


I want to know whether I have simulated the design correctly or am I making some trivial mistake?


I tried to adjust the pin depth and position but not get a good match! Port impedance is 50 ohm. I used wave port for coax port which provide 50 ohm and other side is also a wave port.


Can anyone please help me solve my problem?


Please let me know what all details do you require, I will provide all the details required.


Thank you.
