Calculation of Theta and Phi in HFSS

what is theta and phi?

If those are the locations around the antenna/network, there is no relation with S11, Z etc.

oh!that's bad new for me!

i need to export the phi and theta from hfss automatically, so i don't know any other way i can do that!

can you help me?

What do you really want to export? field patterns/radiation patterns etc. Then you can do it by exporting in .tab, .csv or txt format.

did you atleast plot radiation pattern & field pattern in hfss?

you means epsion et mu?
