Hello,<\/p>\n

I want to simulate a differential pair that is capacitively coupled to a microstrip pair. I made a simplified geometry of my actual resonator. I assigned PerfE boundaries to each microstrip and pad element in yellow. There is no GND plane in this model, the wires act as reference and do not receive direct excitation. I am confused about how to create a port for this model. Any suggestions?<\/p>\n

I added two lumped ports and edited the sources to be 180 degrees out of phase with respect to each other. I was able to create a differential pair under  “Excitations” using this configuration. This does not give errors and can give a solution, but is it physically correct? Thanks.<\/p>\n
