I am able to plot E-Fields (V_per_m) and H-Fields (A_per_m), over the surface of patch antenna, using Field Overlays option. I wish to see, how impedance varies over the patch surface in same manner. Any suggestion, help would be greatly appreciated.
In HFSS13, there is a field calculator cookbook built into the help...in the field calculator cookbook, the whole of the steps are walked through to create a field calculator function that can be plotted for the spatial instantaneous impedance! Search cookbook in the help
