Background
After the fourth generation mobile communication technology 4G/LTE is commercialized in a large scale, data traffic in a mobile communication network is increased dramatically, and the bandwidth capacity of a mobile communication system in a dense user area faces a huge pressure. In response to the limited capacity of a single cell, using a multi-beam antenna, the coverage area of a conventional single sector may be subdivided into multiple sectors, multiplying the capacity of the wireless channel. The invention patent publication CN102570057A proposes a method for generating five beams using a 6 x 6 butler matrix. Each row of the radiation units which are uniformly distributed is connected with the vertical power divider and then connected with the output port of the 6 x 6 butler matrix, and each polarization corresponds to one 6 x 6 butler matrix. However, the operating bandwidth of the technology is only 23.7% (1710-. Patent 201621038190.7 discloses that the grating lobe suppression capability is better by using a horizontally staggered radiation element arrangement. However, the technical scheme realizes the broadband five-beam antenna with a fixed inclination angle, one polarization needs 2 sets of beam forming networks and combines a phase compensation circuit, the structure is complex, the cost is high, the weight is heavy, and the large-scale application and popularization resistance is large.
A stadium gathers tens of thousands or even 10 thousands of mobile communication users in an olympics event, etc., and cell splitting using five beams is still insufficient to cope with the increasing traffic demand. In order to further increase the capacity, it is necessary to develop a base station antenna with more beams, while simplifying the structure of the antenna system and reducing the cost.

The patent No. WO 2017/156635a1 proposes a six-beam antenna with working frequency band 1696-2690MHz based on three layers of patch antenna units, and adopts 6 rows and 14 columns array, because the antenna units of the technology have more layers, more plastic supports, low production and assembly efficiency, and the gap on the floor has large influence on the unit performance, high control precision requirement, and is not beneficial to large-scale production.
