Abstract

This paper presents some techniques to estimate beamforming coefficients in multibeam array fed reflector an-tennas with an imaging geometry generating a large number of beams, of interest for very high throughput satellite (VHTS) systems. A comparative study of these techniques is proposed using an antenna configuration designed to meet VHTS system requirements with full earth coverage. The impact of removing the amplitude information from the elements excitations is also considered with different scenarios. Numerical results in terms of carrier-to-interference (C / I) are reported to compare the impact of the different scenarios and techniques on the performance of the satellite antenna system over the defined coverage.
