Abstract

This paper describes a Ka-band feed system capable of covering the full commercial and military frequency allocations (19.2 to 21.2 GHz for downlink and 29.0 to 31.0 GHz for uplink). The feed offers both right-hand circular polarization (RHCP) and left-hand circular polarization (LHCP) in the transmit and receive frequency bands, making it suitable for installations accessing a number of Ka-band satellites. The feed was designed for an upgrade of an existing Ku-band facility.
