| A new reflectarray cell operating in dual-frequency reflectarray is proposed in this communication to provide two adjacent beams in orthogonal circular polarizations at transmit and receive frequencies (20/30 GHz) in Ka-band. The reflectarray cell consists of two dielectric layers with two levels of printed elements (dipoles and circular arcs). The cell response is characterized for both circular polarizations at each frequency, and the design procedure for a reflectarray based on the proposed cell is described. This concept applied to parabolic reflectarray antennas will allow to produce two adjacent beams per feed at transmission and reception through the simultaneous use of polarization and frequency discrimination, allowing a reduction in the number of feeds and antennas required for current multi-spot satellite in Ka-band. | |
