Hi Friends,
Recently I use hfss to simulate a circular patch loaded with annualr ring antenna. S parameter is ok, but the directivity is below than 1. I seed the air with lambda/10, and the boundary is lambda/4 away from the radiation element, but the result is same. Anyone can give some advice? Thanks a lot!
The parameter from hfss:
