Abstract

The radiation characteristics of solid dielectric horns of rectangular cross-section, excited by a rectangular metal waveguide operating in the dominant $TE_1_0$ mode, have been studied both theoretically and experimentally. The theoretical analysis is based on the modal knowledge of the field distributions around the dielectric structure and over the free-end aperture. The effect of the feed-end radiation is superposed suitably on the free-end radiation to obtain the total far-field pattern. Experimental verification of the theoretical results is obtained by probing the near-field as well as by the measurement of the far-field pattern at $\lambda=3.2 cm$ and $\lambda=3.2 mm$
