Differential Transmission Line EM Simulation

[nesli]

Hello,

I would like to simulate a differential stripline coupler. I could not find how to do it on ADS. Could anyone tell me how to do EM simulations for differential lines? Or is it even possible on ADS?
What software would you recommend for that?

Thanks in advance!

Are you familiar with ADS layout? You can draw the lines manually from polygons and then analyze using Momentum. You can also parameterize the layout for EM, as described in my appnote here:

Yes I am but how I differentiate it from a single ended one. Is it about how I assign the ports?

Yes, you place two pins and map them to one port: one pin is signal terminal (plus) and the other pin is return terminal (minus).

This is done by drag & drop of second pin to minus terminal of the port.
