A dual-polarized base station antenna array

Abstract

An embodiment of the present invention provides a dual-polarized base station antenna array, including a first array element and a second array element parallel to each other; the first array element includes several first radiating elements, and the second array element includes several any second radiating unit; any one of the first radiating unit and any second radiating unit are connected in parallel to the first feeding network based on the first preset power ratio, and the first radiating unit and the second radiating unit are connected in parallel based on the second preset power ratio. It is assumed that the power ratio is connected in parallel to the second feed network. The array provided by the embodiment of the present invention can effectively reduce the influence of mutual coupling between the array elements through the reasonable distribution of power ratio, and realize the convergence of the horizontal lobe of the antenna without increasing the number of antenna radiating elements and the windward area of ​​the antenna, and realize multiple The coexistence of multiple frequency antennas, excellent performance indicators, saving antenna space on the basis of satisfying performance, especially ensuring that the horizontal half-power beam width, front-to-back ratio and other indicators will not affect the cross-area coverage due to exceeding the standard, can be widely used in mobile communication base station antennas.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a dual-polarized base station antenna array. Background technique [0002] With the rapid development of mobile communication technology, communication networks of different standards are integrated with each other, and the requirements for system complexity and quality are getting higher and higher. As the front-end core equipment of mobile communication network coverage, antennas face severe challenges and play a huge role. In recent years, multiple network standards of 2G, 3G, and 4G have coexisted and co-located, resulting in increasingly tight site resources, making it more difficult to open new site resources in cities. In this environment, there are more and more demands for multi-frequency and multi-port base station antennas, and the requirements for performance indicators are becoming more and more stringent. Co-station can greatly...
