microstrip antenna/ie3d

Try with the help of ring and annular sector entity.

I am drawing microstrip antenna in HFSS. In this E boundary of ground and patch is getting overlap. To avoid this overlap what should i do. Thankyou for your suggesion.

you have to define it separately.
can u attach the snapshot of it? so that we can exactly point out .

i am using ie3d simulator for planar antenna design.can anyone guide me how to get co and cross pattern in both E plane and H plane?
