Reflectarrays are becoming increasingly popular for their ability to overcome the bulkiness of reflector antennas, while also combining the advantages that a phased array antenna may provide. Here, a proposal for a reconfigurable reflectarray is presented, with the main novelty being the control of the amplitude of the reflection via individually addressable optically reconfigurable elements. Initially,...
Reconfigurable reflectarrays provide the ability to combine the advantages of reconfigurable phased arrays with the high gain of reflector antennas. Optical reconfiguration provides the ability to continuously change one or more property of the antenna, without the need for extensive RF biasing compensation. To this end, an optically reconfigurable reflectarray has been designed, operating in Ka-Band...
