Dear Community

I’m trying to simulate a Van Atta array in CST Studio Suite  using the true transient solver wit ha dummy in schematic window. The setup seems correct — I can see voltage signals on ports P1 and P2, so the plane excitation works — but I’m not able to generate any Monostatic RCS or far-field results. Later i would like to add another elements (like PA) that's why the workflow with schematic is important. Gain of the antenna looks abnormal as well.

I’ve attached a simplified project with 4 dipole antenna file showing my setup. Could someone please check what might be missing or misconfigured (e.g., excitation, boundary, or solver settings)?

Any guidance or example workflow for obtaining RCS for Van Atta array in this case would be greatly appreciated. 

Thanks,
Pawel
