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: The present disclosure relates to a phase shifter, an antenna, and a radio communications device. One example phase shifter includes a cavity, a rotating shaft, a main printed circuit board (PCB), a first slidable part, and a second slidable part. The first slidable part is located on a front side of the main PCB and coupled to the main PCB. The second slidable part is located on a rear side of the main PCB and coupled to the main PCB. The rotating shaft is inserted into the cavity and connected to the first slidable part and the second slidable part. The first arc-shaped phase delay line and the second arc-shaped phase delay line are distributed on a circle with a center that is the same as a center of the rotating shaft, and are located on an outer side of a primary central coupling section.

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.
