Hi!
I am working on patch antenna design. My supervisors asked me to ensure that I will have infinite ground and substrate dimensions so I decided to use Multilayer Solver. When I am following internet tutorial on how to design coaxial feed for my antenna, I encounter following problem when I try to perform simulation (as in the attachment)
Do you know what could be the solution of my problem? I was trying to resolve this issue for one week now, but without a success.
Best regards,

Konrad
