Problems solved by technology

[0004]The transmission device used for electronic downtilt usually includes a driving mechanism and a driven mechanism. The driven mechanism has a plurality of driven gears. The circumferential direction of the driving gear is distributed circularly so that the driving gear meshes with any driven gear to realize the downtilt angle control of the multi-frequency electric adjustable antenna, so the current electronic downtilt transmission device has a large circumferential dimension

Abstract

The invention relates to a transmission device of a multi-frequency electrically tunable antenna and an antenna assembly. The transmission device comprises a driving mechanism, a rack mechanism and a driving mechanism. The rack mechanism comprises a plurality of racks which are arranged in parallel and located on the same plane, the driving mechanism comprises a driving motor and a gear located on an output shaft of the driving motor, the output shaft of the driving motor is perpendicular to the extension direction of the racks, and the driving mechanism is used for driving the gear to move in the axial direction of the output shaft of the driving motor so that the gear is in meshed connection with any one of the racks, the gear can be driven by the driving motor to rotate to drive the rack to move, the phase of the phase shifter is changed, the downward inclination angle of the wave beam is adjusted, and the racks meshed with the gear are located on the same plane, so that the circumferential size of the transmission device is small and the structure is more compact.

Description

technical field [0001] The present disclosure relates to the technical field of a transmission device applied to a multi-frequency electric adjustable antenna, and in particular to a transmission device and an antenna assembly of a multi-frequency electric adjustable antenna. Background technique [0002] With the increasing number of mobile communication terminal users, the demand for network capacity of sites in the mobile cellular network is increasing. At the same time, it is required to minimize the interference between different sectors of the same site in Shenzhen between different sites, that is, to realize the network Maximize capacity and minimize interference. For this purpose, it is usually realized by adjusting the downtilt angle of the antenna beam. [0003] At present, the ways to adjust the downtilt angle of the antenna beam are mechanical downtilt and electronic downtilt, and electronic downtilt has obvious advantages, which is the current mainstream and fu...
