Hi,

I keep getting empty plotting results after simple patch antenna simulation, the rectangular plot of the S11 parameter is normally plotted, but the radiation pattern and the 3D polar plot remain empty despite following all the right steps.
Can you help me detect the problem?

Thank you very much in advance,
Achilleas

Your plots only start at 0dBi. Probably, the gains are smaller than this. Set the minimum gain to something like -30 dBi and see if that helps.
