Abstract
An optically controlled phase array antenna was characterized at Rome Laboratories Newport Test Site. The wideband antenna has a 500 MHz bandwidth and a scan angle of minus 60 to plus 60 degrees. Five bit photonic time delay modules are the main reason for the large bandwidth capability. A conventional phased array antenna using electronic phase shifters would have on the order of a 50 MHz bandwidth. A wide bandwidth antenna such as this could be used to combine radar, communications and electronic warfare antennas into a single phased array antenna.
