Abstract
A phase shifter includes a base substrate; a signal electrode, first and second reference electrodes all on the base substrate, and the first and second reference electrodes being respectively on two sides of a length direction of the signal electrode; an interlayer insulating layer on a side of the signal electrode away from the base substrate; and a phase control unit including a film bridge on a side of the interlayer insulating layer away from the base substrate. The signal electrode is in space enclosed by the base substrate and the film bridge, and two ends of the film bridge respectively overlap with the first and second reference electrodes in a direction perpendicular to the base substrate. The film bridge includes first and second anchor point areas and a functional area between the first and second anchor point areas, and has a hollow pattern in the functional area.
