The antenna comprises a bottom plate, and a reflecting plate I and a reflecting plate II are respectively arranged on two long edges of the bottom plate; a reflecting plate III is arranged on one short edge of the bottom plate; the bottom plate is provided with a first high-frequency radiation antenna array, a third high-frequency radiation antenna array, a first low-frequency radiation antenna array, a fifth high-frequency radiation antenna array, a sixth high-frequency radiation antenna array, a second low-frequency radiation antenna array, a fourth high-frequency radiation antenna array and a second high-frequency radiationantenna array which are sequentially arranged in the direction from the first reflecting plate to the second reflecting plate. Each array comprises a plurality of high-frequency oscillators I, high-frequency oscillators II, high-frequency oscillators III, high-frequency oscillators IV, high-frequency oscillators V, high-frequency oscillators VI, low-frequency oscillators I and low-frequency oscillators II which are arrayed into a straight line; and first long isolation strips are arranged between the first high-frequency radiation antenna array and the third high-frequency radiation antenna array and between the fourth high-frequency radiation antenna array and the second high-frequency radiation antenna array.

Description

technical field [0001] The invention belongs to the technical field of base station antennas, and in particular relates to a miniaturized multi-standard and multi-band fusion base station antenna. Background technique [0002] With the in-depth construction of LTE networks, operators have put forward higher requirements for mobile signal coverage. Due to the complexity of my country's communication network, it can be predicted that the coexistence of multiple communication application standards will be maintained in the future. Currently, for mobile network signal coverage in venues, high-speed rail stations, and densely-built areas, operators not only need to face the challenge of increasing demand for network capacity, but also face the coexistence of multiple network standards such as 2G, 3G, 4G, and 5G. The problem of high operating costs in the environment. [0003] At present, due to the shortage of antenna resources, in order to make more effective use of site resou...
