MICROWAVE HORN-PARABOLOIDAL ANTENNA

摘要

A horn-paraboloidal antenna in which a discontinuity is introduced into the feed horn so as to excite higher-order modes from the dominant mode. The various modes are phased in order to radiate a main lobe and side lobes from the horn. The latter lobes reflect from the paraboloid out-of-phase with the main lobe so as to produce a far field radiation pattern having a more uniform signal strength for a given beam angle.
