Miniaturized four-low-frequency multi-port base station antenna

Abstract

The invention relates to a compact four-low ultra-wideband base station antenna which is mainly composed of a reflecting plate, low-frequency radiation arrays, isolating strips and an electric bridge.The four groups of low-frequency radiation arrays are arranged on the same plane of the reflecting plate, and the single column of radiation units are arranged at equal intervals and are arranged onthe same axis; the first radiation array and the second radiation array are arranged side by side, the third radiation array and the fourth radiation array are arranged side by side, and the second radiation array and the third radiation array are arranged in a staggered mode. And the isolation strips are arranged among the four groups of arrays. By adopting the PCB vibrator, the weight of a product can be effectively reduced, the transportation cost is reduced, and the installation is convenient; isolation strips are arranged between the arrays; the second column of radiation units and the third column of radiation units are arranged in a staggered way so that the boundary effect between the antenna arrays can be effectively reduced, the mutual coupling of the high-frequency array and thelow-frequency array can also be reduced, and the two columns of radiation units arranged side by side are connected through the bridge so that the antenna size can be reduced to the maximum extent, wind resistance can be reduced, construction and installation are facilitated and production cost can be reduced.

Description

Technical field [0001] The invention belongs to the technical field of base station antennas, and specifically relates to a miniaturized four-low-frequency multi-port base station antenna. Background technique [0002] With the in-depth construction of LTE networks, operators have put forward higher requirements for mobile signal coverage. As my country's communication network is relatively complex, it is foreseeable that a variety of communication application standards will coexist in the future. At present, for mobile network signal coverage in scenarios such as stadiums, high-speed railway stations, and densely-built areas, operators not only need to face the challenge of increasing network capacity requirements, but also need to face the coexistence of multiple network standards such as 2G, 3G, 4G, and 5G High operating costs in the environment. [0003] At present, with the development of mobile communications, spectrum resources are becoming more and more tight. The Ministr...
