Phased Array Antenna Simulation

Question asked by on Dec 29, 2013
I am trying to simulation the beamforming section of a phased array. What would be the best method for doing this? I have seen all the examples talking about radars, but they are all single channel simulations. I am trying to simulate a 4 port reciever. 

If I use an S-port then a bunch of power splitters then it will alter my output noise figure.

I have simulated this manually using AC voltage sources, but not sure if this is the most "elegant" method for ADS

I am only trying to get NF, SNR, G/T out of the sim

Any help would be appreciated
