Abstract
A corrugated feed horn for antenna has an oval pattern of corrugations, and a series of intermediate ridges spaced between adjacent corrugation ridges only in the regions of the slots near its major axis. The intermediate ridges provide a feed horn that is capable of producing a relatively uniform oval beam, and has enough corrugations per wavelength to guarantee little diffraction on the edges of the horn, thus resulting in an antenna with very low side lobes.
