Abstract
Provided herein are various enhancements for feed networks and aperture assemblies in radio frequency transmit/receive systems. In one example an apparatus includes a horn aperture integrated with a multimode feed network that can be monolithically fabricated in a single piece. The multimode feed network comprises a first feed section coupled between a first feed port and a first polarizer port of a polarizer and comprising a first waveguide filter and first waveguide stubs establishing first transmission zeros. The multimode feed network also includes a second feed section coupled between a second feed port and a second polarizer port of the polarizer and comprising a second waveguide filter and second waveguide stubs establishing second transmission zeros. The polarizer comprises a stepped septum positioned between the first polarizer port and the second polarizer port and having a shared port coupled to the horn aperture.
