Abstract
The present invention relates to base station antennas having remote electronic tilt capabilities. Actuators for multiple phase shifters are described herein. An actuator may include a motor, a linkage drive system including a plurality of drive mechanisms for driving mechanical linkages of multiple phase shifters, a linkage selection system that is configured to selectively connect the motor to a selected one of the drive mechanisms of the linkage drive system. The linkage selection system may include a support seat, a carrier disposed on the support seat, and a movement transmission mechanism.

An actuator for multiple phase shifters comprising:
- a motor;
- a linkage drive system including a plurality of drive mechanisms for driving mechanical linkages of multiple phase shifters;
- a linkage selection system that is configured to selectively connect the motor to a selected one of the drive mechanisms of the linkage drive system, the linkage selection system including:
- a support seat having a length direction that is transverse to a length direction of the mechanical linkage;
- a carrier disposed on the support seat and configured to carry the motor back and forth along a length direction of the support seat;
- and
- a movement transmission mechanism that is configured to switch between a movement state in which the movement transmission mechanism is configured to move the carrier and the motor to a position where an output of the motor can engage the selected one of the driving mechanisms, and a transmission state in which the movement transmission mechanism transfers a rotational movement of the output of the motor to the selected one of the drive mechanisms.
