Abstract
The authors present an overview of the development work of a wideband photonic array antenna. They focus on the performance of a unique L-band (850-1400 MHz) 24/spl times/4 element conformal array, supported by a true-time-delay beamforming network. A 2-ns pulse was injected into the system and the round trip impulse response was measured to demonstrate the array´s 550 MHz (50%) instantaneous bandwidth.<>
