Phase-shift circuit and antenna device |
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. |

1. A phase-shift circuit comprising:
a signal line; and a dielectric member overlapping the signal line and being capable of reciprocating in a direction intersecting the signal line, and changing a phase of a signal propagating through the signal line, wherein 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. |
