In order to achieve a wideband and wide-angle electronically scanned antenna, Hughes has been working under an ARPA/Rome Lab Program to develop an L-band 96-element phased array antenna that incorporates fiber optic remoting of RF and digital control signals as well as a true-time delay beam steering mechanism. The true-time delay is accomplished by a combination of fiber optic and microwave stripline programmable delays.
