Hello,
I am working with comsol 4.4, and I know I can use the mode analysis to get the modes of a waveguide or a resonant cavity. However, I wanted to perform a mode analysis of a patch antenna to get the characteristic modes over frequency. Could anyone tell me how to run the mode analysis or the Freuqency-Domain Modal solver with conductive structures? I am currently running a model like that, but none of the mode solutions make any sense.
Thank you.
