Feed development for advanced Satcom RX-antenna application

Abstract

The paper presents the results of the feed development for the Advanced Satcom Rx-antenna. Two design variants have been developed and described in this paper. The first feed design was used to illuminate a dielectric lens antenna, whereas the second is compatible with a multiple reflector antenna system. Both antenna concepts require the use of a feed cluster. A 19-element feed cluster was designed, built and tested for the dielectric lens. A single feed chain was developed for the reflector system. The feed design issues, as well as the measured results are presented in the paper. Excellent feed performance is demonstrated.
