研究提升线性场景5G覆盖能力的新方法

Study a new method to improve 5G coverage of the linear scene

普通的5G天线覆盖距离仅为800 m,不能满足超长桥梁的覆盖需求。本文用球型透镜原理实现单波束高增益,采用多层介质球体的折射特性,将单个天线单元的低增益、宽波束的电磁波信号汇集成高增益、窄波束的电磁波信号,工作原理与光学透镜聚焦原理相似,与普通板状天线对比具有高增益和高垂直瓣宽等优势,可广泛应用于4G/5G场景,有效解决了特大桥梁的覆盖问题,开拓了5G新局面。

The ordinary 5G antenna covers a distance of only 800m,which can not meet the needs of the overlong bridge.In this paper,the single beam high gain is realized by using the spherical lens principle,and the refraction characteristic of the multi-layer dielectric sphere is adopted,the low-gain,wide-beam electromagnetic wave signal of a single antenna unit is integrated into a high-gain,narrow-beam electromagnetic wave signal.The working principle is similar to that of optical Lens focusing,compared with the conventional plate antenna,the antenna has the advantages of high gain,high vertical lobe width and so on.It can be widely used in 4G/5G scene,effectively solve the covering problem of the large bridge,and open up a new prospect of 5G.
