Optimization of corrugated horn radiation patterns via a spline-profile

Abstract

Corrugated horns are widely used as feeds for reflector antennas [1] or as direct radiators, as in global earth illumination from a satellite [2, 3] or as source antennas in an anechoic chamber. Shaping the radiation pattern of a corrugated horn is mainly done by shaping the profile [4-6] to the required aperture dimension, and to a lesser extent, for wideband applications, by using a mode-converter [7-9] tuned to the design frequency.
