Abstract
A new reflectarray cell operating in dual-frequency band is proposed to simultaneously discriminate between orthogonal circular polarizations at transmit and receive frequencies (20/30 GHz) in Ka-band. The reflectarray cell, which consists of two dielectric layers with two levels of printed elements (dipoles and circular arcs), has been characterized for both circular and linear polarizations at each frequency band.In addition to implement the variable rotation technique in a dual frequency operation, the reflectarray cell allows to introduce phase corrections at the receive frequencies. This concept applied to reflectarray antennas in Ka band will allow to produce two adjacent beams per feed in orthogonal circular polarizations at both transmission and reception frequency bands.
