Abstract: A phase shifter may include a cavity body, and a fixed circuit board and a phase shift unit that are located inside the cavity body, and the phase shift unit being capable of moving relative to the fixed circuit board. A power division circuit is disposed on the fixed circuit board. The power division circuit includes an input end, a main feeder, a node, at least two output ends, a filtering stub, and at least two output circuits. The main feeder is electrically connected between the input end and the node. The filtering stub is electrically connected to the main feeder, and the filtering stub is in an open-circuit state. The at least two output circuits are respectively electrically connected between the node and the at least two output ends. The phase shift unit is disposed in correspondence with the at least two output circuits.

Abstract: A phase shifter includes a cavity (100) and a first fixed transmission line (301), a second fixed transmission line (302), and a slidable transmission line (201) that are located in the cavity (100). The first fixed transmission line (301) is provided with a first open slot (3011), the second fixed transmission line (302) is provided with a second open slot (3021), and opening directions of the first open slot (3011) and the second open slot (3021) are opposite to each other. Two ends of the slidable transmission line (201) are respectively clamped in the first open slot (3011) and the second open slot (3021), so that the slidable transmission line (201) is electrically connected to the first fixed transmission line (301) and the second fixed transmission line (302). The slidable transmission line (201) slides relative to the first fixed transmission line (301) and the second fixed transmission line (302).

Abstract: A phase shifter and an antenna, in the field of communications technologies. The phase shifter includes a cavity, and a fixed component, a sliding component, a control rod configured to control sliding of the sliding component, and a dielectric portion in the cavity. A first strip group is disposed in the fixed component, where the first strip group includes two strips. The sliding component is located above the fixed component, and a second strip group is disposed in the sliding component. The second strip group includes two strips, and the two strips of the second strip group are electrically coupled to the two strips of the first strip group respectively.
