Abstract :
A novel phased array concept using a low frequency modulation technique is presented. Any desired shape and any direction of the radiated beam can be generated by controlling the modulation phase of each radiating element which contains a PIN-diode mounted at the feeding point. In order to resolve the ambiguity of the two sidelobes a multistage single sideband detector is incorporated into the system. The operating. principle is discussed and some possible applications are given.
