A combiner/divider includes a plurality of input/output waveguides distributed in a plane and diverging in at least a partially common direction away from a central point. Each input/output waveguide extends from an outer node disposed distal of the central point to an inner port proximate to and spaced from the central point. Each input/output waveguide has a respective dimension in the plane that increases between the inner port and the outer node. An output/input waveguide has an aggregate port proximate to the central point and facing the inner ports. A transition waveguide defines an open cavity that flares outwardly in the plane from the aggregate port toward the inner ports and communicatively couples the output/input waveguide with the input/output waveguides. Opposing distal surfaces of the transition waveguide and inner port edges are spaced apart by a distance that decreases with increasing distance from the aggregate port.

Waveguide combiner/divider having plural input/output ports with longitudinal extent

A combiner/divider includes a transition waveguide interposed between a plurality of input/output waveguides and an output/input waveguide. The input/output waveguides are preferably distributed in a radial sector extending in the E-plane of the input/output waveguides. The input/output waveguides extend from inner nodes disposed proximate to and spaced from a sector center to outer nodes disposed along an arc of the sector. At least some of the input/output waveguides taper in size from the inner nodes to the outer nodes. Walls between adjacent input/output waveguides also may taper in width between the inner nodes and the outer nodes. The output/input waveguide has an inner port facing and spaced from the inner nodes of the input/output waveguides. A transition waveguide extends between the input/output waveguides and the output/input waveguide and has side walls extending along the radii of the sector for communicatively coupling the output/input waveguide with input/output waveguides.
