Reflectarray antennas have attracted significant attention due to a number of attractive properties, such as low cost, and conformal deployment capability. In addition, the drive towards flexible radio transceivers, enabling beamforming and multi-beam operation has spurred significant interest towards the design of antenna elements and antenna arrays with reconfigurable capabilities. A review of recent publications and patents on reconfigurable reflectarrays is presented focusing on the different capabilities, technologies and architectures that have been proposed.
Keywords: Reflectarray antennas, reconfigurable antennas, antenna beam-forming
