The invention relates to the technical field of antennas, and discloses a multi-beam antenna array, a base station antenna and an antenna array decoupling method, and the multi-beam antenna array comprises a decoupling device and a plurality of sub-arrays which are respectively installed on a reflection plate; any sub-array comprises a plurality of radiation units, the decoupling device comprisesa metal sheet arranged between two adjacent radiation units in the sub-array, the metal sheet is T-shaped, and the width of one end, which is perpendicular to the reflecting plate and is connected with the reflecting plate, of the metal sheet is smaller than that of the other end of the metal sheet. The invention provides a multi-beam antenna array, a base station antenna and an antenna array decoupling method. The metal sheet is arranged between the two radiation units, so that the beam isolation between the radiation units is improved, the antenna performance is improved while the physical size of the antenna is reduced, and the decoupling device is simple in structure and can reduce the cost.
Description
Technical field [0001] The present invention relates to the field of antenna technology, in particular to a multi-beam antenna array, a base station antenna and an antenna array decoupling method. Background technique [0002] With the rapid development of mobile communications, the contradiction between the rapid increase in mobile data traffic and the limited spectrum resources has become increasingly prominent. In order to cope with the blowout of traffic and data in scenarios such as crowded shopping malls, venues with frequent competitions, and rush hour routes, how to maximize the efficiency of the site has become the focus of the operators. [0003] Using sector splitting is one of the most effective ways to achieve capacity expansion, that is, dual-beam antenna technology. By beam splitting, the traditional 65° sector is divided into two. Compared with the dual-sector system with two 32° narrow-beam antennas, the dual-beam antenna concentrates two narrow beams on In one a...
