Title:
PHASE SHIFTER DRIVING DEVICE AND ELECTRICALLY TUNABLE ANTENNA
Document Type and Number:
WIPO Patent Application WO/2021/052117
Kind Code:
A1
Abstract:
The present application relates to the field of mobile communication base station antennas, and discloses a phase shifter driving device and an electrically tunable antenna. Specifically, a shift mechanism comprises a push-pull component and at least one clutch gear, a transmission mechanism comprises a transmission gear in one to one correspondence with the clutch gear; the central axis of the clutch gear, the central axis of a driving gear and the central axis of the transmission gear are parallel to each other, the at least one clutch gear is arranged on the periphery of the driving gear along the same circumference, and at least one transmission gear is arranged on the periphery of the clutch gear along the same circumference; there is a space between the clutch gear and the driving gear and/or between the clutch gear and the transmission gear in the central axis direction, and when moving along the central axis, the clutch gear can simultaneously mesh with the driving gear and the transmission gear; the push-pull component is used for selectively pushing the clutch gear to make reciprocating motion along the central axis. The phase shifter driving device and the electrically tunable antenna provided in the present application can realize miniaturization under conventional processes, achieve the purpose of antenna miniaturization and reduce manufacturing costs.
