Title:
PHASE SHIFTING APPARATUS AND ANTENNA
Document Type and Number:
WIPO Patent Application WO/2021/243606
Kind Code:
A1
Abstract:
Disclosed in the present application are a phase shifting apparatus and an antenna. The phase shifting apparatus comprises a phase shifter (1) and a driving assembly (2); the phase shifter (1) comprises a phase shifting substrate (12) and a phase shifting sheet module (13), the phase shifting substrate (12) is provided with an arc-shaped feeding circuit (121), the phase shifting sheet module (13) is provided with a pivoting end which is rotatably connected to the phase shifting substrate (12) and a free end which is opposite the pivoting end, the free end is provided with a coupling circuit (1321) corresponding to the arc-shaped feeding circuit (121), and the coupling circuit (1321) moves along the arc-shaped feeding circuit (121) and is in coupling connection with the arc-shaped feeding circuit (121) when the phase shifting sheet module (13) rotates around a pivot axis of the pivoting end; the driving assembly (2) comprises a driving rod (21) which is rotatably arranged at one side of the phase shifter (1) and a transmission member (22) which matches the driving rod (21); and the transmission member (22) moves along the driving rod (21), along with the rotation of the driving rod (21), to drive the phase shifting sheet module (13) to rotate relative to the phase shifting substrate (12) around the pivot axis thereof. According to the phase shifting apparatus and the antenna provided by the present application, the driving assembly (2) can drive the phase shifting sheet module (13) to rotate around the pivot axis thereof to realize a phase shifting operation, such that the electrical downtilt of the antenna can be adjusted, and the amount of space occupied can be effectively saved on.
