Technical Field
The invention relates to the technical field of antennas, in particular to a micro base station antenna array.
Background
From telegraph, telephone to mobile phone, from 1G to 4G, the communication technology brings endless convenience for human and society, and nowadays, people are coming to the 5G era. The 5G era is no longer just the improvement of network speed from 2G to 3G and from 3G to 4G, but the communication between people is expanded to the connection of everything, and a fully mobile and fully connected digital society is created.
The capacity of 5G is 1000 times of 4G, the peak rate is 10Gbps-20Gbps, and three factors are not needed for improving the capacity and the rate: spectrum bandwidth, spectrum efficiency, and number of cells. At present, the low-frequency end smaller than 3GHz is basically occupied by 2/3/4G, so 5G is expanded to the high-frequency band of 3.5GHz-30GHz (even higher), however, the higher the frequency band is, the poorer the penetration capability is, the smaller the coverage area is, which means that more base stations must be built for the same area to complete the coverage.
At present, the base station which is built in a large scale in China is mainly the macro base station, and the cost for building a 5G macro base station is about 3 times of 4G, so that the optimal solution is sought between the 5G performance and the construction cost, which is a problem that operators tend to solve, and the micro base station is an optimal solution for solving the problem.
The micro base station does not need a special machine room and a return network like a macro base station, so the equipment is simple, the deployment is flexible, the cost is low, the micro base station can be even directly nailed on a wall, or can be built according to places with dense people flow and poor signals, and the quality of indoor network coverage can be enhanced by building the micro base station indoors.
In order to further enhance the coverage performance of the micro base station, the micro base station may be formed with an antenna array according to a related technology, where the micro base station antenna array includes an antenna cover, a radiation unit, and a calibration network composite board, and the antenna cover may protect the radiation unit and the calibration network composite board in the cover. Compared with the installation of a macro base station antenna array, the installation of the micro base station antenna array is simpler, firstly, the cost is reduced, and secondly, the micro base station antenna array is convenient to detach for inspection and maintenance, but the micro base station antenna array is easier to steal by lawbreakers, and the safety is insufficient.
