Phase shifter medium structure, phase shifter and base station antenna

Abstract

The invention relates to the technical field of base station antennas, and discloses a phase shifter medium structure, a phase shifter and a base station antenna. The medium structure is arranged on the carrier plate inside the cavity of the phase shifter and comprises multiple groups of medium components which are arranged at intervals along the length direction of the carrier plate. Each group of medium components are fixedly connected with an inner pull rod. One end of the inner pull rod extends out of the cavity of the phase shifter to be fixedly connected with an outer pull rod. Accordingto the phase shifter medium structure, the phase shifter and the base station antenna, multiple groups of medium components are arranged at intervals so that the medium consumption covering the carrier plate can be reduced and the cost of the phase shifter can be reduced in comparison with a large mass of medium structure at present; besides, the loss of microwave passage can be reduced, the lossof the phase shifter can be reduced and the antenna gain can be improved because of reduction of the medium area; in addition, each group of medium components do not need to be customized for the specific phase shifter, and the medium structure can be applied to other phase shifters so as to improve the applicability of the medium structure.

Description

technical field [0001] The invention relates to the technical field of base station antennas, in particular to a phase shifter dielectric structure, a phase shifter and a base station antenna. Background technique [0002] As the final control terminal of the mobile communication network, the antenna of the communication base station makes the final adjustment to the network provided to the user. The phase shifter is the core component of the base station antenna. The phase shifting function of the phase shifter can meet the needs of the same type of antenna in different areas of use and different communication load areas to achieve different electrical downtilts, so as to provide greater network capacity and reduce Small communication interference, reduce labor costs. [0003] Existing dielectric phase shifters generally use striplines in the form of PCBs, with a set of dielectrics on each side of the PCB, and the PCB is sandwiched between the media. One end of the medium...
