Design of corrugated conical horns
Abstract
Details of the design of circumferentially corrugated conical horns are presented. Radiation pattern and phase-center characteristics for both 'wide-band' and 'narrow-band' horns are considered, and a comparison is made between the relative sizes of the two types of horns. The effects of horn aperture size, slot width-to-pitch ratio and frequency on the cross-polarization of the radiation pattern are included. The range of slot parameters which can be used and the design of the slots near the throat of the horn to achieve a low VSWR for bandwidths of 1.5 to 1 are also considered. The results of measurements on horns with both narrow and wide included angles are given.
