Advanced Reflectarray Antennas for Multispot Coverages in Ka Band

Abstract

This contribution proposes three different multibeam antenna farms based on reflectarrays to be used on board broadband communication satellites in Ka-band. The proposed antenna configurations make it possible to generate multispot coverages in a more efficient way than the antenna systems currently used, since they require a smaller number of antennas on board the satellite. Simulated results are presented for the three antenna configurations to evaluate their compliance with the system requirements.
