A reconfigurable aperture-coupled reflectarray element is proposed for the realization of beam steering antennas, suitable for radar applications. Each reflectarray element is coupled to a microstrip line, which is loaded by a single varactor diode acting as a phase shifter element, thus providing a continuously variable reflection phase. A reduced size reflectarray unit cell is properly designed in order to extend the antenna beam scanning capabilities within a wide angular region, but avoiding the occurrence of undesired grating lobes. The radiating structure is properly optimized to obtain a full phase tuning range at the frequency of 11.5 GHz, thus assuring a good agility and accuracy in the reconfiguration of the reflectarray radiation pattern.
