Abstract

A full wave hybrid numerical technique is presented for the analysis of horn antennas with general cross section interior taper and arbitrarily shaped outer surface. A mode matching (MM)/ edge based two-dimensional finite element (FE) method is employed for the generalized scattering matrix (GSM) of the stepped-waveguide model of the inner horn taper. The exterior problem is solved by employing a Method of Moments (MoM) procedure with Rao-Wilton-Glisson (RWG) basis functions, to evaluate the Generalized Scattering Matrix (GSM) of the radiating aperture. Inner and outer GSMs are therefore connected to obtain a full wave solution for the overall radiating structure.
