Abstract :
Single frequency band antenna systems for satellite communications are gradually evolving into multi-band antenna systems. The complexity of the feed in these systems increases when dual circular polarization and simultaneous high power emission and low noise reception are required for each band. It is not always possible to integrate multi-band feeds into small antenna apertures because the feed tube of these systems has to be large enough to host all the feed components. This paper describes a single-horn 1.9 m antenna, C/X dual band, transmission and reception, dual circular polarized feed system. The frequencies of operation are: Rx-C, 3.4-4.2 GHz; Tx-C, 5.85-6.65 GHz; Rx-X, 7.25-7.75 GHz; Tx-X, 7.9-8.4 GHz.
