Abstract : The patent describes a retrodirective transponder wherein pairs of elementary radiators are connected by equal lengths of transmission lines so that the re-radiated wavefront is parallel to the incident wave front permitting the reradiated signal to be beamed in the direction of the illuminating transmitters. The re-radiated wavefront is frequency translated from the incident wave to avoid ringing of the transponder.
