Abstract
This contribution presents preliminary results of a 1.8-m reflectarray antenna proposed to generate a complete multi-spot coverage for transmission in broadband satellite communications in Ka-band. The antenna is designed according to a recently validated design method of reflectarrays which allows to produce four adjacent beams per feed by discriminating simultaneously in frequency and polarization. The simulations consider 27 dual-polarized feeds to illuminate the reflectarray, so the 1.8-m reflectarray is expected to generate 108 beams separated 0.56 degree at two frequencies and two polarizations. The concept enables a reduction in the number of antennas and feeds required on board geostationary communication satellites to provide multi-spot coverages in Ka-band.
