[Problem] To add a function that makes it possible to vary wavelength in a waveguide that is provided with a ridge-shaped conductor and a columnar conductor within a parallel flat plate structure. The adding of said function makes it possible to reduce the size of a phase shifter that has an input/output port fixed thereto and to thereby reduce the size of a phased array antenna that comprises a plurality of phase shifters. [Solution] A plurality of protruding shapes or recessed shapes are provided on a conductor plate that is on a side that is not provided with a ridge-shaped conductor and a columnar conductor, and a mechanism is provided that causes the conductor plate to move in a direction that intersects the direction in which the ridge-shaped conductor extends. In addition, the protruding shapes or the recessed shapes between adjacent phase shifters are changed by a fixed quantity, each conductor plate is configured from a single member, and a mechanism is provided that causes each of the conductor plates to move relative to one another in a direction that intersects the direction in which the ridge-shaped conductors of the phase shifters extend. |
