Abstract :
The input impedance of the hemispherical cavity-backed slot antenna is investigated theoretically and experimentally. The mode-matching method and moment method are used to find the Green´s function of the cavity and the equivalent magnetic current of the slot, respectively. The effects of slot length and cavity radius on the input impedance are studied
