Abstract

A few versions of impulse antennas are studied with the aim of suggesting an optimal design of the feed line and radiator for the reflector-based antenna and ensuring operation of the facility at high voltages and under field conditions. The high-voltage system described as the final choice is intended for shaping and radiating electromagnetic pulses of ultrashort duration, while maintaining the proper electric strength of its components. It is characterized by an electrodynamic potential (field-range product) W = 1.2 MV. The system is a variant of the half-reflector impulse antenna design, involving a half-circular parabolic reflector that is excited through a nonuniform dual-line feeder of simple geometry.
