A hollow waveguide directional coupler comprises two hollow waveguide sections that are coupled to each other by a plurality of coupling openings formed in a wall extending between the hollow waveguide sections. Two adjacent coupling openings have a distance of 3&#x3bb;/4. from each other, &#x3bb;being the wavelength of the nominal center frequency of the operating frequency range of the directional coupler.

Hollow waveguide directional coupler

A compensating arrangement for two aligned, angularly relatively offset, end-to-end positioned wave guides of identical cross section. The compensating arrangement has a plate member inserted between face-to-face arranged terminal flanges of the two wave guides. The plate member has an aperture corresponding to the cross-sectional area of the passage defined together by the two wave guides; and two oppositely located capacitive loads extending into the aperture and being symmetrically located with respect to the bisector of the angle defined by the minor transverse axes of the wave guides. The capacitive loads are reactance members for a broad-band compensation for the discontinuity between the angularly offset wave guides.
