lumped port for different structure

[orcid]

Hi,
How can I define lumped port for cylindrical, triangular or other self-made structures?
Is it wrong to define rectangular shape for lumped port in such these structures?
Thanks

Using lumped ports is the easiest way to define excitation in HFSS. Just create a rectangle at the feeding gap and then assign a lumped port on it.

Thanks streamlet
I guessed lumped port shape is dependent to structure; but you are right.
