Abstract

High-power microwaves are generated using high voltage (HV) pulses, which are generated using a Marx generator connected to a peaking stage. The output of the peaking stage is the input to the half transverse electromagnetic (HTEM) horn-type antenna. This paper discusses the effect of isolation distance between HV tapered arm and the grounded reflector on the variation of characteristic impedance and gain with respect to the length, flair angle, and tapering angle of the antenna. This paper also discusses the radiation loss on the side and back of antenna. An experiment has been described using an available Marx generator and HTEM antenna. Using the experimental and simulation results, the optimal design parameters of antenna are obtained.
