hello Md Siam Talukder ,

If you have set your far-fields properly, after the simulation process, you will find both the co and cross-polar outputs as in the attached image.

Before the simulation, go to "Field-Monitor" and set farfield for the desired frequency.

After the simulation, go to Farfields (below 2D/3D results)>> Your desired frequency and you will find the polarizations.

look at this paper it's interesting for you!

Md Abdul Kaium Khan Many thanks for your response. So here phi=co-polar , theta=cross-polar?

Md Siam Talukder

Yes! and the best way is to verify from the polar plot. Cross polar will have less gain (more negative decibels) than Co-Polar.

Best Wishes!
