How to excite with a circular polarized wave using Floquet porst in HFSS?

Hi,
I'm trying to excite a floquet port with a circular polarized wave, but I can't find the way.
What I'm doing instead is calculating the results by calculating the fields for the floquet modes 1 and 2 [S(floquet1:1,floquet1:1) and so on...
My goal is to mesure the axial ratio and the S parameters.

Is there another way of setting the floquet port?

Thanks a lot
