Design of the Optimal Feed System for High Power Microwave Antenna System

In this paper, the optimal feed system which is located between source and reflector antenna is suggested for the miniaturization of high power microwave (HPM) antenna system. The suggested feed system is fabricated in order to examine and measured radiation patterns that agree with the calculated patterns are obtained. As a result, this feed system has high gain about 27 dBi. Return loss is less than -23 dB at 10 GHz and the -25 dB beamwidth of the radiation pattern equals to 29deg in H-plane
