Abstract

The invention discloses an antenna transmission device and an antenna. The antenna transmission device comprises a driver, a first transmission mechanism, a guide rod, a second transmission mechanism and a phase shifter connected sequentially, wherein movement of the driver output shaft drives the guide rod to move via the first transmission mechanism, and the movement direction of the guide rod is vertical to that of the driver output shaft; and movement of the guide rod drives the phase shifter pull rod to move via the second transmission mechanism, and the movement direction of the phase shifter pull rod is the same as that of the driver output shaft. By adopting the transmission device of the invention, the movement of the driver output shaft can be transversely transferred to the phase shifter pull rod, and the phase adjustment precision of the phase shifter can be ensured.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an antenna transmission device and an antenna. Background technique [0002] Various types of communication antennas such as base station antennas need to be tilted downward relative to the horizontal line at a certain angle when they are working. This angle is the downtilt angle of the antenna. The adjustment of the downtilt angle can directly affect the radiation effect of the antenna. The phaser lever changes its phase. The accuracy of the drive directly affects the adjustment accuracy of the downtilt angle. [0003] In the prior art, the movement of the motor is transmitted to the pull rod of the phase shifter to realize the drive, and the transmission is mostly realized by an adapter plate. However, for antennas with a large lateral transmission distance, the adapter plate itself is easily deformed, resulting in the movement of the motor and the Inconsistent movemen...
