Analysis of conical corrugated horn antenna operating with high power pulses

摘要

This paper presents an analysis of a conical corrugated horn antenna operating using high power pulses. The main goal was to design an antenna structure with the capability of handling 1 GW peak power. During the design process, the antenna breakdown strength, number of corrugations and possibility of filling the structure with SF_6 gas or high vacuum were taken under consideration. To obtain a hermetic antenna, some thin dielectric plate in the antenna aperture and dielectric lens were considered.
