I am using HFSS to design a microstrip antenna.
I have not too much experience with simulation program
and I have problems with the definition of the ports.
I am not sure which kind of ports are more suitable
for my design because I need to look for at least
5 of the propagation modes and for example with
a "lumped port" I can look only at one of them.
Have somebody of you experience in the definition
of ports in microstrip structures and can give me
a piece of advice to undestand how they work with
Thank you very much
