Original Abstract Submitted
A phase shifter includes: transmission channels that have one ends connected to an antenna element, are formed with a gap, and have different lengths; movable electrodes that are provided to the gaps, and move in a direction parallel to the transmission channels to be switched to an on-state in which the movable electrode overlaps transmission channel end portions on both ends of a corresponding one of the gaps and is inductively coupled with the transmission channel end portions and to an off-state in which the movable electrode does not overlap at least one of the transmission channel end portions on both ends of the corresponding gap and is not inductively coupled with the at least one of the transmission channel end portions; and MEMS mechanisms that change a phase difference by switching the movable electrodes to one of the on-state and the off-state to switch lengths of the transmission channels.
