nI tried HFSS and Q3D. In both cases, I made a 50mmx50mm parallel plate capacitor with 2mm of FR4 dielectric in between. I get the capacitance value correct, but I think I have to use the DrivenModal solution type in HFSS for getting the impedance vs freqeuncy plot like I mentioned above. Also, I can't get how to assign (and where) a lumped port, I think I have to use this as well. nIt will helpful if you outline the process of getting the graph I need (as I mentioned above) in Q3D (or in HFSS).nThank you.n
