Abstract

The invention relates to the technical field of wireless communication, in particular to a miniaturized six-high multi-port base station antenna which comprises a reflecting plate, high-frequency radiation elements and four paths of high-frequency radiation antenna arrays composed of the high-frequency radiation elements, and isolating bars I arranged in the length direction of the arrays are arranged among the four paths of high-frequency radiation antenna arrays. The periphery of each high-frequency radiation element is provided with a second isolation strip, a third isolation strip is arranged between the adjacent high-frequency radiation elements in the same array, the third isolation strip is arranged between the second isolation strips on the periphery of the adjacent high-frequency radiation elements, and the first high-frequency radiation antenna array and the fourth high-frequency radiation antenna array are arranged on the two sides of the reflecting plate. The second high-frequency radiation antenna array and the third high-frequency radiation antenna array are arranged in the middle of the reflecting plate, and the four high-frequency radiation antenna arrays are arranged in a staggered mode. According to the six-high multi-port base station antenna, the requirement of a six-path high-frequency radiation antenna array is met by utilizing the four-path high-frequency radiation antenna array, the size of the antenna is effectively reduced, and the miniaturization of the antenna is realized.
