| titleOfInvention | Directional coupler |
| abstract | A multi-terminal directional coupler consisting of a combination of a plurality of directional couplers. Two coupling conductors (18a, 19a and 18b, 19b) constituting the directional couplers are so formed as to be opposed to each other on both sides of a grounded conductor via dielectric substrates (10a, 10b) and cut-away portions (17a, 17b) are provided in the grounded conductor at portions where the coupling conductors are opposed to each other. The coupling conductors are electromagnetically coupled to each other via the cut-away portions. Therefore, no interference takes place between the transmission lines on both sides of the grounded conductor, and the multi-terminal directional coupler is realized in a small size and in a reduced weight. |
