I am trying to simulate Microstrip line to get the S-parameter.
but I don't know how to set the boundary and excitation ?
is there any example for me to reference ?
I think what you want to do is right click on setup1, then select "properties". On the first tab, UNcheck "solve ports only". I believe this will allow for s-parameter calculation, but I'm not totally sure and can't explain why that even makes sense...
