Multi-port base station antenna

The invention provides a multi-port base station antenna. The multi-port base station antenna comprises a reflecting plate, at least one group of low-frequency radiation arrays and at least one group of high-frequency radiation arrays. The at least one group of low-frequency radiation arrays and the at least one group of high-frequency radiation arrays are arranged on the reflecting plate in parallel or in an overlapping manner; a gradually-changing boundary group is arranged between each group of low-frequency radiation arrays or each group of high-frequency radiation arrays, and the gradually-changing boundary groups are located on the reflecting plate. By arranging a flexible combination mode of the high-frequency radiation array and the low-frequency radiation array on the reflecting plate, the antenna size is reduced, the horizontal beam width is effectively reduced, and the front-to-back ratio is improved. 本发明提供一种多端口基站天线，包括：反射板、至少一组低频辐射阵列和至少一组高频辐射阵列；所述至少一组低频辐射阵列和所述至少一组高频辐射阵列在所述反射板上采用相互平行或重叠进行排列；每组低频辐射阵列
