Problems solved by technology
Although the common dynamic antenna switching technology on the market implements beam switching for each antenna, the three antennas do not point in the same direction at a certain moment.
That is to say, when the end user cannot receive the signals of the three antennas at the same time, the MIMO performance is discounted
[0017] B. Antenna design: Since the dynamic antenna switching technology uses a simple two-choice RF switch, so in the case of ensuring the best MIMO performance and ensuring omni-directional coverage, there are only two antenna switching methods for each RF output, namely Switch between two semi-circular antenna beams pointing to different points. Therefore, compared with narrow beam directional antennas, the half-power angle of this antenna element is too large, resulting in too large a channel competition window at the same time, and the channel competition is still fierce.

The invention discloses a smart antenna system for oriented narrow wave selection. The system comprises three ring array antennas: a top layer ring array antenna, a middle layer ring array antenna and a bottom layer ring array antenna which are laminated and provided with the same central shaft; each ring array antenna comprises n oriented radiation antenna array elements, wherein n is an positive integer not less than 2, each oriented radiation antenna array element covers a sector region in 360 DEG / n, n oriented radiation antenna array elements are led out from the coaxial line and welded on an interface of a single-pole n-throw switch of an antenna control panel; the top layer ring array antenna and the bottom layer ring array antenna are horizontally polarized antennas, and the middle layer ring array antenna is a vertically polarized antenna. One end of the same yagi sub-antenna is positioned between two adjacent array elements in the bottom layer ring array antenna, and the other end is positioned between two adjacent array elements corresponding to the adjacent array elements in the top layer ring array antenna, so that three ring array antennas are in an orthogonally polarized ring antenna array lamented structure.
Description
technical field [0001] The invention relates to an antenna system, in particular to an intelligent antenna system for directional narrow-wave selection. Background technique [0002] WIFI technology has become a very popular communication technology because of its many advantages. WIFI applications have also gradually become the mainstream technology in the commercial market from early home applications. [0003] However, due to some characteristics of the commercial market that differs from the home market, WIFI technology has many defects in the commercial process, which has become a pain point for users. The commercial market differs from the domestic market in the following points: [0004] 1. Large number of end users: [0005] Common applications in the commercial market such as shopping malls, high-speed rail stations, conference rooms, exhibition halls, hospitals, and large offices, etc., are characterized by a large number of users. An ordinary home-level router...
