Antenna array, base station antenna and antenna index improving method

Abstract

The invention relates to the technical field of wireless communication, and discloses an antenna array, a base station antenna and an antenna index improving method. The antenna array comprises high-frequency radiation units and is characterized by further comprising coupling boundaries, wherein the coupling boundaries are of a metal sheet structure, and the coupling boundaries are arranged on oneside or two sides of at least one high-frequency radiation unit. According to the antenna array, the base station antenna and the antenna index improving method provided by the invention, the coupling boundaries are set based on a surface current coupling technology, and the surface current of the high-frequency radiation units is coupled to the coupling boundaries through beam forming, so that the coupling boundaries generate weak radiation and synthesize a narrow beam with the high-frequency antenna array, and the high-frequency horizontal wave width convergence of the antenna is improved.The antenna array has low requirements for the installation space by arranging the sheet-shaped coupling boundaries, the high-frequency horizontal wave width convergence can be improved under the condition that the occupied space is small, the miniaturization and light weight of the antenna can be achieved, and the windward area and weight of the antenna can be reduced.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an antenna array, a base station antenna and an antenna index improving method. Background technique [0002] With the development of mobile communication technology, antenna resources are becoming more and more scarce, and the amount of mobile data is increasing. Antennas are gradually developing in the direction of multi-standard, multi-port, and miniaturization. The requirements for antenna indicators such as wave width and gain are also getting higher and higher. Therefore, the current miniaturized multi-frequency multi-port antenna has become the main development trend of mobile communication antennas. [0003] The horizontal wave width of the antenna is one of the indicators to measure the coverage effect of the antenna. In the miniaturized antenna, the coupling between the arrays or the size of the reflecting surface limits the convergence of the horizontal...
