Simulation study on parachute-type high power EMP radiator

Abstract

Rotating parabolic reflector antenna combined with parachute is designed to have a parachute-type high power EMP radiator. With EM array complementary radiation as the design idea, a four-feed-arm parachute-type reflector antenna structure with higher feeding efficiency is proposed, thus to strengthen the low-frequency radiating capacity, widen the bandwidth of antenna and improve the radiant efficiency of antenna; a balanced feeding structure is also adopted to strengthen the radiating capacity. The results showed that parachute-type radiator is superior to TEM horn antenna in both peak-to-peak value of field strength and effective bandwidth of radiation field, thus making effective radiation of high-power UWB-EMP come true.
