Abstract

In this paper we propose new technology for combining X and Ka band prime focus feed for use in satellite earth terminals with simultaneous transmit/receive in circular polarization and also with tracking opportunity. The paper discusses the electrical and mechanical design of Ka band choke horn integrated with X band eleven feed formed by two parallel dipoles over ground plane. The simulated results show input reflection coefficient better than -15 dB and feed patterns give aperture efficiency better than -3 dB over X as well as Ka band for 50deg half subtended angle of reflector.
