Abstract: A transmission device for a base station antenna includes a motor, a screw driven by the motor, a transmission shaft, and a linkage system. The linkage system is connected with the screw via the transmission shaft, so that the screw drives the linkage system via the transmission shaft. The linkage system includes: a worm driven by the transmission shaft, a worm gear meshed with the worm, at least one spur gear disposed on a same connecting shaft as the worm gear, and at least one connecting rod engagement element. The spur gear and the worm gear are fixed relative to each other. The connecting rod engagement element has a rack meshed with the spur gear, so that the worm drives the worm gear to rotate with the spur gear, and the spur gear drives the connecting rod engagement element via the rack to move in an axial direction of the transmission shaft.

Abstract: The present disclosure relates to a phase shifter, which includes: a phase shift circuit board with conductive traces printed thereon; and a phase shift circuit board with conductive traces printed thereon; and a slide device with a first tooth section configured to be driven, wherein movement of the first tooth section drives the slide device to slide on the phase shift circuit board. In addition, the present disclosure further relates to a remote electrical tilt system, which includes an actuator, a transmission mechanism, and at least one phase shifter according to the present disclosure, wherein the actuator is configured to drive the transmission mechanism, and the transmission mechanism engages the first tooth section to drive the slide device to slide on the phase shift circuit board. In addition, the present disclosure also relates to a base station antenna which includes the remote electrical tilt system according to the present disclosure. The base station antenna according to the present disclosure may improve the stability of the transmission of the remote electrical tilt system and increase the space utilization of the remote electrical tilt system.
