CST Antenna Coupling

Hi, 

I'm new to CST and antennas and I would like to evaluate the antenna to antenna coupling between two antennas on a satellite.

I have two quadrifilar helix antennas. Each antenna is fed with two discrete ports.

Do you know how to get the antenna to antenna coupling?

when you put TWO probes you'll get S11 for the interactions as S12 and S21  in the S-parameters results...

discrete ports are the probes i'm talking about...coupling is directly calculated every time you use more than one port

Yeah but one antenna has 2 discret port (1 and 2) and the other has 2 discrete ports (3 and 4).

 

I need the coupling between [1,0]+[2,90] and [3,0]+[3,90].

I hope I was clear

Thanks Admin but I didn't find the answer i wanted.

I try to explain better: since my design is very large, I'm using field sources and when I use field sources I have the F-parameters.

I don't get them, are they like S-parameters? I just need to quantify the antenna to antenna coupling
