摘要：<p>TITLE WAVEGUIDE WITH DIELECTRIC LOADED FLANGE ANTENNA FEED INVENTORS Apisak Ittipiboon Lotfollah Shafai Ernest Bridges The antenna feed includes a waveguide radiator with a conductive flange positioned about the waveguide near its radiating end. A dielectric element is positioned about the waveguide between the flange and the radiating end and establishes the dielectric surface impedance seen by the waveguide. The dielectric element may consist of one or more layers of dielectric material to form a composite dielectric. One of the layers may be an air gap adjacent to the flange. The size and position of the flange and dielectric element will control the radiation pattern of the beam from the feed.</p>
