Hi. I want to plot polarization of a patch antenna. I'm using HFSS, but that shouldn't make a difference because my questions regard the topic of polarization and not the simulator.
My patch radiates in the negative z-direction. It should be circularly polarized. I want to know how to measure this.
From the pic: phi sweeps around the x-y plane & theta sweeps around the z-axis.
I think I want to plot the polarization ratio when theta is 180 degrees since that is the direction of maximum gain. What should I choose for phi? I want to compare the electric field of Ex to Ey. I think that's correct.
Do I need to plot gain in the x-dir and gain in the y-dir?
Please let me know. thanks.
