UWB monopole circular-shaped microstrip antenna

Hello everyone,

Can anyone send me an example for designing UWB monocle circular-shaped microstrip antenna using the AWR software. I have already been working out for 4 months but I still unable to get it operates on 3.1GHz -10.65GHz. For your information, I am still a beginner in using the AWR software so basically I still do not know how to design the ring-shaped antenna as well as create the partial ground plane.

I am looking forward to any reply.

Thank you so much
