Hello!
I am using COMSOL RF module (emw, frequency domain) to simulate transmission line antennas. I excite my antennas using a lumped port. This is because I want to define a ground plane. Now, in the same setup I would like to incorporate ports to calculate s-parameters. These should ideally be placed between close to the lumped port and in between the lumped port and the antenna system. However, ports can only be defined on boundaries. So I am stuck here.
My question is whether both ports and lumped ports can be incorporated in the same setup in the same feeding lines. Or if it is possible to define a ground plane without using a lumped port (does port excitation off also mimics a groundplane?).
Thanks for all the help I can get! Remmert
