Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to an antenna including a beam forming apparatus.
Background
Cell signal coverage in mobile communications is achieved by installing base station antennas at the base stations and having beams covering the planned area. According to the change of factors such as the geographic characteristics of cells, user distribution and the like, the radiation direction of the antenna beam of the base station needs to be adjusted. The adjustment of the radiation direction typically includes a beam downtilt angle in the vertical dimension and a beam azimuth angle in the horizontal dimension.
The adjustment of the vertical downtilt and the horizontal azimuth can be divided into two categories according to the implementation: the first is to adjust the physical position of the whole base station antenna by mechanical means; the second type is that the physical position of the base station antenna is not changed, and the phase of signals of each unit in the antenna is changed by adjusting the phase shifter in the antenna, so that the beam pointing change is realized. The first category of solutions is generally implemented by designing the rotatable means on the mounting bracket of the base station antenna and the electrically controlled power take-off means in the antenna. The second scheme is generally implemented by designing a phase shifter connected to each unit and a controller capable of controlling phases of output ports of the phase shifter in an antenna, that is, a mechanical adjustable electrical downtilt (MET) device or a remote electrical downtilt (RET) device.
With the increasing of systems and frequency bands of mobile communication, it is increasingly difficult to obtain site resources, and site sharing (i.e. each network operator shares the same site location) becomes a main appeal for operators. Under the condition of site sharing, in order to avoid visual pollution caused by too many antennas with different frequency bands mounted on the top of the base station tower and increase the load bearing load of the base station tower, a multi-frequency antenna, i.e. one antenna integrating multiple frequency bands, has become an important trend in the development of base station antennas. In order to enable a multi-band antenna to have the beam-pointing adjustment function described above, it is obvious that the first type of physical adjustment scheme is not satisfactory, while the second type of physical adjustment scheme requires the installation of a phase shifter and a corresponding MET or RET device for each frequency band within the antenna. The second scheme has the defects that the number of control devices in the antenna is too large, the volume of the antenna is obviously increased, and the like. The defect is particularly prominent for a multi-frequency antenna of an integrated radio frequency unit (RRU), such as an active antenna processing unit (AAU), because the multi-frequency antenna has a larger volume than a single-frequency antenna, and the size of the integrated RRU is further increased, which poses a challenge to the environmental reliability (e.g., wind load performance) of tower top equipment. Secondly, in order to ensure the stability of the broadband access characteristic of the user, the user-level beam must change in real time according to the user distribution characteristic, which requires the multi-beam forming device to have a quick response capability. For the above technical reasons, achieving miniaturization and fast response of multi-driven MET or RET devices is a fundamental complaint for successful application of such antennas.

Integral miniaturization facilitating multi-beam antennas
In particular, the drive means may be a mechanical drive means or an electromechanical drive means. The drive of the embodiment shown in fig. 2 is an electromechanical drive comprising an external interface (such as the 485 interface of AISG), a motor, a control board, a mechanical interface and a housing. The drive device drives a load, such as a first drive shaft and a second drive shaft, to the outside via the drive shafts of the mechanical interface. The electromechanical driving device receives a control signal and a power supply through an external interface, the motor is driven according to the control signal, and the motor drives the first driving shaft and the second driving shaft to rotate, so that power is provided for the selection device and the driven device.

Optionally, the profile of the cam shaft may be an isosceles trapezoid, the bottom of the cam shaft is disposed on the side of the cylindrical rod, and the area of the bottom of the cam shaft may be greater than that of the top of the cam shaft, so that the two sides of the cam shaft are inclined inward, thereby more effectively pushing the driven member to connect the driven member and the output member in the process of contacting the driven member.
(2) One of the selectable structural forms of the selection device is a sliding block structure:
as shown in fig. 4, the first driving shaft of the selection device is coupled to the second output shaft of the driving device by a pair of bevel gears. The second shaft has a threaded structure, which can be called a threaded rod, and the selection member of the selection device, which is coupled with the thread of the second shaft and is non-rotatable relative to the second shaft, also has a threaded structure. The second drive shaft drives the selector member along the axis of the second shaft.

At the same time, the return spring assembly is also compressed, and the A locking of the return spring assembly to the coupling is released. When the selector is disengaged from the coupling B, the coupling B is then disengaged from the coupling a by this return spring assembly. Meanwhile, the coupler A is locked through friction resistance torque under the action of the return spring assembly, the driven piece is not easy to be driven by the rotation driving device, and the selection device is connected with the output piece through the selection driven piece, so that the driving device selectively drives the output device.

(1) alternatively, as shown in fig. 1 and 7, the driven member and the output member are connected, and the end faces of the driven member and the output member for connection are provided with convex teeth which are distributed in the circumferential direction. When the driven member is selected by the selection device, the convex tooth part of the end surface of the driven member is meshed with the groove part (tooth groove) of the end surface of the output member, so that the output member can be driven to rotate when the driven member rotates;
(2) optionally, as shown in fig. 4 and 5, the driven member and the output member are two couplers which are used in cooperation, such as a coupler a and a coupler B shown in fig. 8, and when the driven member is the coupler a, the output member is the coupler B; when the driven part is a coupler B, the output part is a coupler A. When the driven member is selected by the selection means, the driven member engages the output member to effect rotation of the output member when the driven member is rotated.
