Hi,
I do a simulation about microstrip line based one the driven terminal soultion type.I set up two waveport one the two ends of the ustrip.But I find that the mesh is diffrent from the two sides.This causes the S11 or Zo is different at two port.This obviously is incorrect.May I make some adjustment to let the mesh symmerty?

Thanks for your help
Sincerely, Jslee
 

There is no way to make mesh symmetrical, but you can refine it in both ports.
So, if ports are equal, the difference will be negligible finally
