Hi,
I've made a model a two port stacked patch antenna using HFSS.
Hove do I get input impedance of such antenna? I used results - Z parameters - Z(waveport1, waveport1) but I get strange results. The real part is bigger than 50ohm. (see picture). After I deembed the ports 1 and 2 the impedance at 705MHz (resonance) is 76ohm, and at 710MHz 50ohm (as it should be). Is this correct? I know the differece is just 5MHz but still...!

You could use the port Zo feature in the post processor. Look for details in on-line help.
