Good Morning,

I am developing a complex GPS system, with integrated logic and antenna.

Since now I am simulating the PCB stackup using momentum, and then adding the lumped components later in ADS co-simulation.

The limitation that I found are the impossibility to evaluate the radiation diagram variation due to the components, and the impossibility to correctly evaluate the surface current densities, as all the unused ports are teminated on 50 Ohm loads.

Is there a way to include lumped components into Momentum simulation, so that the results are more realistic?

Thanks

Simone
