Analysis of a Flanged H-Plane Horn with Dielectric Slab in Aperture

Abstract

An H-plane sectoral horn with the rectangular waveguide feed is studied using the generalized scattering matrix (S-matrix) method and domain-product technique (DPT). The structure incorporates dielectric slab flush with the flanged aperture. The excitation mechanism involves the dominant mode. Calculated radiation characteristics have been presented for several configurations.
