wideband circular polarized

hi all!
im a new guy here..i need some help regarding my project..anyone knows how to distinguish whether it is a good circular polarized or not.Here i attach .geo and .pat for your review.Tell me if i did wrong in simulation.

Thanx

anyone help pls!...

sorry i havent used any ie3d. but look at your axial ratio at theta (0)

below 4db gives good circulation ratio

good luck
