Abstract

The invention relates to the field of mobile antennas, and provides a transmission device and an electrically-tunable antenna. The device comprises a transmission assembly. The transmission assembly comprises first bevel gears, second bevel gears, a transmission shaft, gears and racks. The first bevel gears are meshed with the second bevel gears, the first bevel gears are used for being connectedwith an external driving mechanism, the second bevel gears and the gears are connected to the transmission shaft in a sleeving mode, the gears and the racks are more than one and are arranged in a one-to-one correspondence mode and meshed with one another, and each rack is used for being fixedly connected with a movable medium of a phase shifter. According to the transmission device, the rotationdirection of transmission is changed through cooperation between the first bevel gears and the second bevel gears; the plurality of gears can be arranged on the transmission shaft as required, so thatthe phases of a plurality of phase shifters can be synchronously adjusted by means of one external drive, the synchronization precision of phase adjustment is ensured, a required space can be provided for arrangement of more phase shifters, miniaturization of the antenna is facilitated, materials are reduced, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mobile antennas, in particular to a transmission device and an electric adjustable antenna. Background technique [0002] With the rapid development of mobile communication technology, mobile communication has entered the 5G era. Correspondingly, the following new requirements have been put forward for 5G mobile communication base station antennas: First, the number of radiating units, that is, oscillators, has increased. Thirty 5G antennas with more than two radiating elements tend to be common; secondly, due to the design requirements of thinner and thinner, the volume of radiating elements in the 5G era is significantly reduced, and the design of 5G antennas tends to be lighter and thinner. [0003] The performance and applicability of the electronically adjustable antenna are stronger, and it has been widely verified in the 3G and 4G era. The development of the 5G electronically adjustable antenna is ...
