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.

A cable and a high-frequency device are provided to reduce passive intermodulation interference. The cable includes a strip line and a coaxial line. The strip line includes (in an outer-to-inner sequence) a strip-line outer conductor, a strip-line signal cavity, and a strip-line inner conductor. The coaxial line includes (in an outer to inner sequence) a coaxial-line outer conductor, a first insulation medium, and a coaxial-line inner conductor. The cable further includes a coupling ground plane provided with a coupling aperture portion. The coaxial line is disposed in the coupling aperture portion, the coaxial-line outer conductor is coupled to the coupling ground plane, the strip-line outer conductor is connected to the coupling ground plane, and the strip-line inner conductor is connected to the coaxial-line inner conductor.
