Hi Fatiya,


Have you created the two arrays explicitly in one FEM domain? 

If you are interested in the far field patterns, you simply assign proper amplitude and phase to the ports. To do that, right click on the Excitation in the project manager, go to Edit Sources, and there you can assign whatever amplitude and phase. You can keep the receiving antenna with 0 for excitation and excite the transmitter ports accordingly. 

If you are concerned about the power coupled between the two antennas, then respective S parameters can give you that information. 

We do have specific workflows for finite array antennas (which is more beneficial as the size of the array gets bigger). If you have access t customer portal, submit a service request and we can guide you on the finite array workflows.
