Hi,
I am simulating a Coplanar Strip Line on ground plane. I m using waveport at one end with 2 modes....and differntial port with reference impedance of 100Ω in differential mode and 25Ω as common mode reference. The waveport is normalized to 50Ω impedance. I am connecting a lumped element say a resistance of 100 Ω at other end of the coplanar strip line. I am defining it by a rectangle of lumped RLC boundary.

hi, maybe you can choose HFSS->solution type->driven terminal, then, you can assign waveport, you will see that differential mode and common mode. hope help for you!~
