Abstract
A high gain non-mechanical steerable beamforming antenna is provided together with a system implementing the antenna. The steerable beamforming antenna uses a reflectarray structure in conjunction with a phased array antenna element configuration. The antenna elements may include micro particle arrays (MPAs), having a number of micro particles disposed thereon. The micro particles may be implemented as graphene elements or as plasmonic elements having a sufficiently high electron mobility and an electron carrier density that is controlled as a function of an applied electronic tuning signal. The change in electron carrier density of the MPA elements, in turn, causes a phase change in incident waves provided by a source feed, facilitating steering of a main beam of an antenna pattern associated with the reflected incident waves.
