Hi 

in this pic,

blue is ground plan, and green is signal lines.

this scheme is stripline but ground has apertures

and left side ,That is PerfE, and  I set wave port at right side face in PerfE box , in DrivenTerminal

wave port is bigger than substrate height, because signal line has radiation upside at aperture part in ground plane.

 

but I got error messages see the sentences with underline

How should I set wave port in better way?

Hi, 

It seems like you have selected multiple conductors while defining the port. Make sure that only one conductor has been selected as a signal trace.

Please refer to differential pair or stripline example in HFSS. 

I hope this will help.
