Integrated Antenna Received Power Simulation

I have simulated the antenna structure in HFSS, and made the .s1p file which I have imported to ADS and connect rest of the circuits.

Now,

1. In the receiver design, the antenna receives power which will be fed to the next stage (LNA/Mixers etc). Generally antenna response is extracted into 1-port S-parameter touchstone file (from HFSS) and connected to the next part, then how can I feed received RF power at RF frequencyto the next stage in simulation, so to say antenna port power? Here, I am adding one port s-parameter file of antenna as black box having another port as reference which is made to ground, but I can't simulate(Harmonic Balance) the rest part as I cant feed the power to the next stage like using P1_Tone termination. Here, the antenna port impedance is not 50ohm, rather it is complex conjugately matched to the next stage, so cant replace s1p block by simply P1_Tone with Zo=50. As antenna is integrated to the LNA, so antenna terminal is connected to the LNA input, here how can Iimplement antenna port power with the EM simulated layout of theintegrated structure?

2. Will there be any added advantage if this integrated antenna design is made into EMPro?

The "normal" workflow is to simulate the antenna and the circuit separately.

For simulating the circuit, you can use a source with the impedance value that you have calculated for the antenna.

Thank you for the help.

Suppose the antenna Zin = A + jB; in case of circuit, the source impedance (ADS TERM Zo value) would be equal to A + jB, so that the rest part (having Zin = A - jB) is conjugately matched to the antenna. => is it correct?
