Phased Array Simulation

Hello Everyone !

I'm simulating a linear 4 elements patch array on ansoft designer v2.2 at a single frequency

I've placed, in the planarEM, the four patches with separate ports.

Now I need to view the antenna beam moving with the phase difference of the port excitation.

If i simulate the network and, after, i visualize the far-field, there is obviously a broadside beam because the phase difference is zero. . If i varing the phase difference in the port definition ,it moves along the tetha axis.

How can i animate it to view the entire theta sweep ? I need a parametric simulation ? how can i do it ?
