how to simulate the RCS of an antenna array with an active circuit network?
The RCS simulation in HFSS is modeled as a incident wave port or Floquet port excitation and the feed port (coaxial cable) is set as a match load. I need to connect the feed ports with an active circuit network, which is will affect to RCS even if the circuit network is not activated. The co-simulation of ANSYS supports to extract the s parameter in HFSS and import to circuit model. However, it didn't support that import the circuit model to HFSS. it seems that we need to import the circuit model to HFSS.
