Abstract
Easy technique to compute the required phase to tilt a pencil beam to the desired direction is proposed. This require phase is added to the reflected fields by the variable rotation technique (VRT) in reflectarrays printed on parabolic surfaces fed by a single dual circular polarized (CP) horn. The proposed reflectarray cell for VRT is made of a conductive cross printed on a grounded dielectric. To demonstrate the multibeam capacity a 1.8-meter offset parabolic reflectarray has been designed to generate six beams in circular polarization with three dual-CP feed-horns, with very promising results for multi spot beam satellite antennas in Ka-band.
