Hi. I've simulated an antenna array with lumped ports as the feed for each of the 4 antennas. I thought that after simulation I could just change the phase and the 3D Polar plot and Radiation Pattern plot would change when I view their reports (radiation plots).

Am I doing something wrong? Thanks.

I think if you change the phase of your ports after your initial simulation, you must run the simulation again to see the changed results.

Sorry. I made a mistake. Everything is fine and you don't need to resimulate. I didn't see that the magnitudes of the other lumped ports were 0. I had to change them to 1. Sorry about that. kevinj.
