X- Ka dual band prime focus feed for satellite earth terminals
Paper i proceeding, 2009
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 -15dB and feed patterns give aperture efficiency better than -3dB over X as well as Ka band for 50° half subtended angle of reflector.
