Hello everyone.
If I want to simulate a SMA connected source to a microstrip fed patch, should I use lumped ports or wave ports?
I am having this confusion as when I am using wave ports using sizing guidelines provided in the manual, a message is coming where it is showing that the port supports an extra propagating mode. But when I am adding more modes in the port definition and visualizing the port field display, I think the extra mode isn't correct. So my question is does SMA connectors only allow the quasi TEM mode in a microstrip or shall I allow another mode as the cutoff frequency(again obtained by plotting imaginary value of gamma in HFSS) is coming lesser than my operating region.
Or using lumped ports with integration line from feed line to ground plane will give the more realistic results?
