Phase shifting device and base station antenna

Abstract

The present disclosure provides a phase shifting device and a base station antenna. The phase shifting device comprises a driving module, a transmission rack plate, and a plurality of annular phase shifters. The driving module comprises a transmission rod. The transmission rack plate comprises a transmission nut, through which the transmission rack plate is pivotally connected to the transmission rod of the driving module. The plurality of annular phase shifters are disposed on the periphery of the transmission rack plate at intervals and are respectively engaged with the transmission rack plate. The rotation of the transmission rod drives the transmission nut to move back and forth on the transmission rod, and along with the back and forth movement of the transmission nut, the transmission rack plate drives the plurality of annular phase shifters to rotate.
