Abstract

An optical beamforming network for phased array antennas based on a spatial light modulator is experimentally demonstrated. Far-field antenna patterns between 7.5 GHz and 8.5 GHz have been measured showing beam steering capability, amplitude distribution weighting and multibeam operation.
