ABSTRACT:
A transition is provided between a first rectangular waveguide and a second circular wrapped rectangular waveguide. The second waveguide takes the form of an elongated metallic annular wall having upper and lower ends and a partition member extending radially inward from the annular wall and having an inner edge located near the central axis of the annular wall. The partition member extends longitudinally for a length corresponding with that of the annular wall. An elongated metal probe is secured to the lower end of the partition member. The first rectangular waveguide has parallel rectangular broad walls interconnected by narrower walls. The first waveguide is oriented perpendicular to the central axis of the annular wall and has a circular aperture in one of the broad walls facing the lower end of the second waveguide with the aperture being in coaxial alignment with the annular wall. The first and second waveguides are secured together in such a manner that the probe extends through the aperture into the interior of the first waveguide.
