Our project deals with miniaturization of patch antenna. We were successful in reducing the resonant frequency from 5 GHz to 2.41 GHz by simulation using HFSS. But the gain of the antenna we obtained after miniaturization was -1.7 dB. We are confused with this. Is there any problem if the antenna gain is negative. (the gain before miniaturization was 6.9db). please help..
