Hi, I'm now using HFSS to simulate a differential spiral. Since most of the HFSS examples available are single-ended, could anyone here please advice me how to assign excitation to the differential ports and the common-mode port?

Thank you very much.

Anyone? Please!!!

Thank you!
 

You should use lumped port to define a differential port in HFSS. Place a rectangular sheet between the spiral arms and assign a lumped port to it. Hope it helps!
