PROBLEM TO BE SOLVED: To provide a waveguide type 90°hybrid coupler that is advantageous in suppressing radio wave transmission loss. SOLUTION: A circumferential surface of a main body 32 comprises a first side surface 42, a second side surface 44, a third side surface 46 and a fourth side surface 48 which mutually have the angle of 90°while sequentially intersecting. Flanges for waveguide connection are respectively formed projectingly on the first side surface 42, the second side surface 44, the third side surface 46 and the fourth side surface 48, a first port 50 is formed at the center of the flange 40 of the first side surface 42, a second port 52 is formed at the center of the flange 40 of the second side surface 44, a fourth port 56 is formed at the center of the flange 40 of the third side surface 46 and a third port 58 is formed at the center of the flange 40 of the fourth side surface 48. A first wave guide 34 connects the first port 50 and the second part 52, and a second waveguide 36 connects the third port 54 and the fourth port 56. COPYRIGHT: (C)2008,JPO&INPIT
