Two-low four-high multi-port base station antenna

The invention provides a two-low four-high multi-port base station antenna. The two-low four-high multi-port base station antenna sequentially comprises a first low-frequency radiation array, a third high-frequency radiation array, a fourth high-frequency radiation array and a second low-frequency radiation array from top to bottom, wherein the first low-frequency radiation array and the first high-frequency radiation array are arranged in a superposed manner, and the second low-frequency radiation array and a second high-frequency radiation array are arranged in a superposed manner. Therefore, the size of the antenna is reduced, the horizontal beam width is effectively reduced, the front-to-back ratio is improved, the low frequency of 790-960 MHz can be supported and the high frequency of 1710-2170 MHz can be supported by the antenna. 本发明提供一种两低四高多端口基站天线，由上至下依次为第一低频辐射阵列、第三高频辐射阵列、第四高频辐射阵列以及第二低频辐射阵列；其中，第一低频辐射阵列和第一高频辐射阵列叠合布设，第二低频辐射阵列和第二高频辐射阵列叠合布设，在缩小天线尺寸的同时，有效降低水平波束宽度，提高前后比，可覆盖低频790-960MHz、高频覆盖1710-2170MHz。
