phase shifter and antenna

It includes conductor assembly and rotating arm that the present invention, which discloses a kind of phase shifter and antenna, the phase shifter,；Conductor assembly includes the first conductor segment and the second conductor segment；It is assumed that the first conductor segment and the second conductor segment are respectively relative to reference center and are arranged concentrically using any point as benchmark center；Rotating arm can be rotated using reference center as axis of rotation along the first conductor segment and the second conductor segment；It is set on rotating arm there are two coupling part, one of coupling part can be erected in the first conductor segment and be of coupled connections with the first conductor segment, another coupling part can be erected in the second conductor segment and be of coupled connections with the second conductor segment；First conductor segment has the first output end and second output terminal, and the second conductor segment has third output end and the 4th output end.The embodiment of the present invention can make phase shifter connect the radiating element of different number by rotating rotating arm, to change the vertical beamwidth of antenna, be suitble to different covering scenes, and phase shifter structure design is simple, realizes the adjusting to beam angle.
