ANGLE BEND OF WAVEGUIDE DUCT Russian patent published in 2018 - IPC H01P1/02 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering, namely to the elements of the waveguide duct, and can be used in waveguide, antenna and microwave measuring equipment. Angular bend of the waveguide duct contains the input and output rectangular waveguides located at an angle of α relative to each other, in which the walls are parallel in the plane of the bend, as well as the matching heterogeneity. In this case, the matching heterogeneity is made in the form of two conjugate segments of rectangular waveguides, in which the walls are parallel in the plane of the bend and located at an angle of 0°<α<180° relative to each other, and the outer and inner walls form common ribs, the sections of the segments of the rectangular waveguides being different from the cross-sections of the input and output rectangular waveguides to which they are interfaced, while the longitudinal axes of the segments of the rectangular waveguides are parallel to the longitudinal axes of the input and output rectangular waveguides.

EFFECT: increase in manufacturability due to simplification of the design with simultaneous preservation of its technical characteristics.
