摘要： A phase shifter includes dielectric members including facing portions facing a signal line formed on a surface of a substrate and being made of a dielectric material, a supporting member configured to support the dielectric members and receive a moving force for moving the dielectric members in a direction which is parallel to the substrate and crosses the signal line, and a moving mechanism configured to apply the moving force to the supporting member. At least either the dielectric members or the supporting member is provided with a protrusion configured to keep a distance between the facing portions of the dielectric members and the signal line.

摘要： A phase-shift circuit being smaller in size than a conventional phase-shift circuit and being capable of causing a phase difference equivalent to or larger than that in the conventional phase-shift circuit between an input signal and an output signal is achieved. A phase-shift circuit includes: a signal line; and a dielectric member overlapping the signal line and being capable of reciprocating in a direction intersecting the signal line, and changes a phase of a signal propagating through the signal line. The dielectric member is configured of a frame body and a dielectric plate provided inside the frame body and having an overlapping area with the signal line increased or decreased by the reciprocation, and the frame body has a permittivity lower than a permittivity of the dielectric plate.
