- the antenna system in the embodiment of the present invention includes multiple Bartlett matrix modules, more differently directed beams can be output, and the beams cover different regions, so that the frequency can be multiplexed, and the spectrum utilization rate can be effectively improved.
- the signal of the Butler Matrix module of Figure 6 has changed.
- the signal of one channel includes two signal components, the signal component of which has been phase-shifted by the TRX array module, thereby omitting the 90-degree 3dB bridge, thereby further simplifying the structure of the Butler matrix module, and is more suitable for integration. cut costs.
- the embodiment of the invention further includes a base station, which includes the antenna system in the embodiment of the invention.
- the embodiment of the invention further includes a system, the system comprising the base station.
- the disclosed systems, devices, and methods may be implemented in other ways.
- the device embodiments described above are merely illustrative.
- the division of the unit is only a logical function division.
- there may be another division manner for example, multiple units or components may be combined or Can be integrated into another system, or some features can be ignored, or not executed.
- the coupling or direct coupling or communication connection shown or discussed may be an indirect coupling or communication connection through some interface, device or unit, and may be electrical, mechanical or otherwise.
- the components displayed for the unit may or may not be physical units, ie may be located in one place, or may be distributed over multiple network units. Some or all of the units may be selected according to actual needs to achieve the objectives of the solution of the embodiment.
- each functional unit in each embodiment of the present invention may be integrated into one processing unit, or each unit may exist physically separately, or two or more units may be integrated into one unit.
- the functions may be stored in a computer readable storage medium if implemented in the form of a software functional unit and sold or used as a standalone product. Based on such understanding, the technical solution of the present invention is essentially or a part contributing to the prior art or a part of the technical solution.
- the points may be embodied in the form of a software product stored in a storage medium, including instructions for causing a computer device (which may be a personal computer, server, or network device, etc.) to perform various embodiments of the present invention All or part of the steps of the method.
- the foregoing storage medium includes: a U disk, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk, and the like, which can store program codes. .
