Description
Technical Field
The invention relates to the technical field of communication, in particular to a modularized transmission device and a multi-frequency antenna.
Background
In a mobile communication network, the coverage area and signal interference are often changed by adjusting the radiation angle of an antenna, so that the operation quality of the communication network is improved. The radiation angle of the antenna is often realized by driving a phase shifter in the antenna by a transmission device to generate phase change. A mobile communication antenna (e.g., a multi-frequency antenna) often has multiple phase shifters that are often not synchronized and are independently adjusted.
Currently, most of the phase shifters of the antennas are driven individually by a motor and a set of transmission devices; for the multi-frequency antenna, a plurality of phase shifters are built in, and the adjustment of the plurality of phase shifters is often realized by configuring a plurality of motors and transmission devices. However, on one hand, the plurality of motors and the transmission devices occupy the space inside the antenna, so that the difficulty of the layout of the antenna structure is increased, and even the overall size of the antenna is increased; on the other hand, the cost of the whole antenna is obviously increased, and meanwhile, the motor and the transmission device are attached to the phase shifter for placement and installation, the installation is scattered, and the assembly efficiency is low.
The adjustment of the corresponding radiation angle is also different due to the different frequency bands of the antenna or the difference of the designs of the phase shifters, which is shown by the inconsistent phase shifting distance of the phase shifters. For example, on a multi-frequency antenna with both low frequency and high frequency, the phase shift distance of the low frequency is sometimes more than one time of that of the high frequency; or on the high-frequency dual-frequency antenna with different frequency bands, the phase shift distances are still different. Therefore, the difference and uncertainty of the phase shift distance of the phase shifter bring difficulty to the design of the transmission device.
In summary, in order to meet the requirement of rapid development of communication, a transmission device is urgently needed to be designed, the existing distributed transmission device is integrated, the assembly efficiency is improved, the installation space is reduced, and the requirement of miniaturization of an antenna is met; meanwhile, the structure is compact and flexible, the cost is low, and the use requirements of antennas in different frequency bands are met.
