Novel miniaturized multi-frequency antenna array

The invention discloses a novel miniaturized multi-frequency antenna array, which comprises an antenna structure for realizing various functions, a circuit array consisting of various reflecting circuits and isolating bars, and a circuit board consisting of a phase shift circuit and a power division circuit. A plurality of isolation technologies are matched, and the technologies are distributed in a multi-frequency antenna array, so that on one hand, the antenna can radiate a high-gain electric field under the conditions of ensuring miniaturization and light weight of the array, good working of respective frequency bands and non-interference; and on the other hand, the four paths of oscillators work in a space which can only accommodate three columns of oscillators originally in a high-gain and high-isolation state, the overall cost is low, disassembly is convenient, and the antenna has very strong competitiveness in a future multi-antenna base station array. 本发明公开一种新型小型化多频天线阵列，包括实现各种功能的天线结构、由各种反射电路及隔离条所组成的电路
