Patch antenna coaxial feeding help CST MWS

[adigoyal2000]

Hello all,

I am a newbee in antenna designing, I am having problems in designing even a basic coaxial fed patch antenna in CST MWS.
My basic problem is designing the coaxial feed. Through various tutorials I have learned how to create a coax feed but my design always throws an error "Port 1 is inhomogenously filled within the first 3 mesh cells".
It would be really helpful if somebody can help me figure out this basic stuff. I can share the design even anyone wants a look.

Thanks a lot.

Hello,

I think this **broken link removed** will be helpful to you. Basically, you replace the micro-strip input port with your coaxial part via impedance matching and it should work.
