Near-field analysis of H-plane hollow sectoral dielectric horn antennas

Abstract

This paper deals with the H-plane hollow sectoral dielectric horn antenna. The metallic wall of the metal horn antenna is replaced by dielectric sheets to obtain this type of antenna. Attempts are made to determine theoretically the approximate fields on the aperture of the antenna under several simplifying assumptions. A comparison is made between theoretically calculated and experimentally observed values for one of the components (the amplitude) at the front aperture of the antenna. © 1990 Taylor and Francis Ltd.
