Abstract

The invention discloses a phase shifter transmission device and an antenna. The phase shifter transmission device comprises a pull rod drive assembly, a gear transmission assembly and a phase shifter assembly, wherein the pull rod drive assembly is connected to the gear transmission assembly in an engaged mode, the phase shifter assembly is connected to the gear transmission assembly in a rotating mode, and the linear motion of the pull rod drive assembly is converted into curved motion of the phase shifter assembly through the gear transmission assembly. According to the phase shifter transmission device, small torque of the linear motion of a pull rod can be converted into large torque through gear transmission, and a phase shifter is driven to make curved motion.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a phase shifter transmission device and an antenna. Background technique [0002] With the development of communication technology, antennas are gradually developing in the direction of miniaturization and multi-frequency, and the components that occupy the largest layout in the antenna include phase shifters. The existing phase shifters include electrical downtilt and mechanical downtilt. However, the existing phase shifters cannot meet the requirements of high-precision transmission and small size. Contents of the invention [0003] The invention provides a phase shifter transmission device and an antenna to solve the problem that the phase shifter in the prior art cannot meet the requirements of high-precision transmission and small size. [0004] In order to solve the above technical problems, the present invention provides a phase shifter transmission device, which ...
