<p>A waveguide structure is described wherein a section of waveguide is effectively shorted at one end thereof by a pair of conductive plates. Each of the plates is adjacent to a narrow wall of the waveguide section and extends from broad wall to broad wall across the aperture of the waveguide. The edge of one of the plates remote from the edge adjacent to a narrow wall is closely spaced from the remote edge of the other plate to form a gap between the edges midway between the narrow walls. The thickness of the plates and the spacing of the gap between the plates is arranged so that no appreciable radiation occurs due to the gap at the reflective end.</p> |
