Multi-Spot Beam Reflectarrays for Satellite Telecommunication Applications in Ka-Band
This paper describes a reflectarray concept that can produce a full dual-band (transmit/receive) multiple spot beam coverage in Ka-band using only two main apertures while maintaining single-feed-per-beam operation. The proposed concept combines the capabilities of the reflectarray and a parabolic surface, enabling the antenna to radiate more than one beam types in the typical ”4-color” frequency polarization re-use scheme. Preliminary results using single-band array elements are presented and confirm the potential of the proposed concept.
