SINGLE 90-DEGREE ANGLE BENDING IN N-PLANE IN RECTANGULAR WAVEGUIDE STRUCTURE Russian patent published in 2020 - IPC H01P1/02 

FIELD: physics.

SUBSTANCE: invention relates to microwave devices. Invention is single 90° angular bending in the H-plane, characterized by that between the wide bending walls and perpendicular to them two cylindrical metal rods are installed, the axes of which are located at certain distances from both narrow walls, wherein distance from each outer wall to each of axes of rods is 0.546 × A and 0.172 × A with diameter of each rod 0.126 × A, where A is wide width of waveguide wall.

EFFECT: technical result is to ensure operation of angle bend in full working frequency range of used waveguide at level of return losses of not more than -30Db.
