A rectangular waveguide elbow formed with a truncated beveled corner on its outer edge and formed with a conductive cross bar which extends between the narrow walls of the waveguide and which is positioned midway between the inner corner of the waveguide elbow and the center of the truncated wall and further including an extending electrically conducting cylinder mounted on the interior surface of the truncated wall with its center on the diagonal of the truncated wall. The diameters of the conductive cross member and of the conductive metal cylinder are chosen so as to minimize the reflection factor and thus to reduce the reflection factor over a relatively broad-band. |
