Ka Band Compact TE21 Tracking Feed System

Abstract

This paper deals with the design of compact TE21 based monopulse tracking feed system in Ka Band for satellite communication. It also deals with the coupling mechanism of TE21 mode by using slots along the circular waveguide. The paper describes the design of the axial corrugated horn used for illuminating the reflector antennas in communication satellites. It also reports the integrated performance of TE21 Tracking coupler and axial corrugated feed with a septum polarizer. The proposed structure was designed for the frequency range of 22.5 GHz to 27.0 GHz.
