I run simulation of microstrip antenna in HFSS 11. I expect to get a gain of antenna at most 10 dBi but when I use Results ----> Create Far Fields Report -------> Rectangular plot ----> Etheta ----> dB I get about 20 dB. It could not be in dBi.
In HFSS 10 I would get this quantity in dBi but in HFSS11 I dont understand why it doesn't .
