The propagation behaviour of a corrugated cylinder is considered with particular reference to the application of such structures to hybrid-mode feeds for large reflector antennas. Results are presented which relate to the design of narrow-flare-angle horns of circular cross-section. These include the parametric dependence of a number of special points on the propagation curves. A procedure for achieving a balanced hybrid condition in the horn aperture is discussed following the proposal made by Bryant.read more

Optimum design of a Gregorian-corrected spherical-reflector antenna
TL;DR: In this article, the performance of spherical reflector antennas with Gregorian correctors is investigated with particular reference to their application in satellite-communications ground stations, and an optimum subreflector profile is chosen on the basis of maximum overall efficiency for a particular feed and antenna-scan angle.
