DEVICE FOR POLARISATION PLANE TURN Russian patent published in 2008 - IPC H01P1/165 H01Q15/00 

FIELD: radio equipment.

SUBSTANCE: contains section of wave conductor (1) with short-circuiters (4, 5) at the ends and two mutually perpendicular rectangular slots at the inlet (2) and outlet (3). Section of wave conductor (1) with matching reflector (8) has rectangular section and length equal to the size of wide wall, at that rectangular slots (2, 3) are provided on its both wide walls. Wide wall of rectangular slot at the inlet (2) matches rib that is formed by crossing of wide and narrow walls of wave conductor section (1), and wide side of rectangular slot at the outlet (3) matches rib that is formed by crossing of short-circuiter (5) and other wide wall of wave conductor section. Inside section of wave conductor matching straight prisms are installed (6, 7) with size of base side (0.52±0.2)b and length (0.9±0.1)(a-b), where a, b - sizes of wide and narrow wall of rectangular wave conductor section. Flat matching reflector (8) with length of (0.9±0.2)(a-b), inclined at the angle of 45°±5° to the narrow wall of rectangular wave conductor section, is installed between narrow wall and short-circuiter.

EFFECT: reduction of longitudinal size and expansion of working range of frequencies.
