ABSTRACT:
A waveguide element is formed of a body of plastics resin, such as, acrylonitrile-butadiene-styrene resin, having a tubular portion open at its opposite ends and flanges directed outwardly at such ends, and a conductive layer, for example, of an electroless plated metal such as tin-cobalt alloy, covering the inner surface of the tubular portion and the surfaces of the flanges which face axially in the directions that the respective ends open. For ease of molding or forming the body of plastics resin, such body may be comprised of a pair of complementary parts divided at a plane extending longitudinally in respect to the tubular portion, with such parts having mating flanges directed outwardly along their longitudinal edges and with the conductive layer also covering the confronting surfaces of the mating flanges.
