The object of this invention is to provide a low-cost, monolithic antenna structure for electronically-controlled beam scanning operable at millimeter-wave frequencies. A further object of the invention is to provide an antenna design of monolithic geometry which is adaptable to batch fabrication techniques such that numerous devices may be simultaneously and identically produced. The millimeter-wave electronic scan antenna according to the invention comprises a semi-insulating dielectric waveguide having a semi-conducting epitaxial layer on at least one side surface of the guide with distributed schottky barrier control elements deposited on the epitaxial layer. Periodic slots in the upper surface of the guide act as radiating elements while beam scanning is effected by varying the bias voltage across the schottky barrier element.
