摘要： The present disclosure provides a phase shifter and an antenna. The phase shifter includes: a substrate; a signal electrode, and a first reference electrode and a second reference electrode respectively on two sides of an extending direction of the signal electrode; an interlayer insulating layer on the signal electrode, the first reference electrode and the second reference electrode; and at least one phase control unit each including a film bridge. At least part of the at least one phase control unit further includes at least one driving structure including at least a driving electrode; at least part of the at least one driving structure has a different height from a height of the signal electrode in a direction away from the substrate; the driving structure in each phase control unit is at least partially overlapped an orthographic projection of the film bridge on the substrate.

摘要： A phase shifter and an antenna device are provided. The phase shifter includes a substrate, a signal line on the substrate, ground lines in pairs on the substrate, and a capacitance adjusting component. Two ground lines in a same pair of ground lines are on both sides of the signal line and spaced apart from the signal line, respectively. The capacitance adjusting component includes a film bridge, and both ends of the film bridge are on the two ground lines, respectively. The signal line is in a space enclosed by the film bridge and the substrate. The capacitance adjusting component is configured to adjust a capacitance between the film bridge and the signal line to a target capacitance when the capacitance adjusting component receives a bias voltage, and the target capacitance has a linear correlation with a magnitude of the bias voltage.
