cst radiation efficiency
Hi,
I have simulated a simple probe fed circular patch antenna using CST on two different substrate - FR4 and R03010. The resonant frequency (S11) results look fine with both having resonant frequency around 867MHz.
But, I notice that the radiation efficiency / total efficiency from the far field result at the resonant frequency is very low (which leads to very low gain). Therefore, may I know whether I am doing the correct far field simulation? Is there any setting which I have done wrong? Please help.
Attached is the CST file with the results. Thanks.
