The invention discloses a base station antenna, a calibration network device and a phase shifter, the phase shifter comprises a cavity, a phase shift circuit board, a phase shift medium piece and a debugging medium piece, the cavity is provided with a shielding cavity and a debugging hole penetrating through the side wall of the shielding cavity, and the shielding cavity is provided with an inletand an outlet; the phase shift circuit board is fixedly arranged in the cavity and is arranged in the shielding cavity; the phase shift medium piece can move relative to the shielding cavity through the inlet / outlet; the debugging medium piece comprises a medium body, and the medium body is movably arranged in the shielding cavity through the debugging hole and used for adjusting the standing-waveratio of the phase shifter. According to the phase shifter, the standing-wave ratio can be adjusted in a non-tin-adding and non-tin-reducing mode, and the intermodulation hidden danger easily causedby tin-adding and non-tin-reducing operation can be avoided. The calibration network device adopts the phase shifter, so that the efficiency of adjusting the standing-wave ratio is higher, and the antenna performance can be improved. According to the base station antenna, the calibration network device or the phase shifter is adopted, so that the standing-wave ratio is convenient to adjust, and better antenna performance is obtained.
Description
technical field [0001] The invention relates to the technical field of antennas, in particular to a base station antenna, a calibration network device and a phase shifter. Background technique [0002] With the rapid development of mobile communication networks, communication systems are rapidly evolving towards 5G. 5G antennas have become an important research direction at present, but they are still facing many problems. [0003] The phase shifter is the core device of the base station antenna, and it is also a key device that affects the electrical performance and radiation performance of the base station antenna. At present, the phase shifter is composed of multiple components, each component has a certain dimensional tolerance, and there is also a mechanical fit error between each component, which causes a certain fluctuation in the standing wave ratio of the phase shifter. The existence of fluctuations in the standing wave ratio of the phase shifter makes the standing...
