摘要
5G网络建设下电磁环境日益复杂,电磁干扰现象也逐渐严重。分析了5G MU-MIMO大规模天线阵列的应用场景和特点,并对吸波材料的电物理特性进行基础探究。采用甲基硅橡胶材料作为吸波体单元结构原材料,以适应5G天线室外使用要求。设定了技术路线和吸波体材料、形状、尺寸等参数,并设置波导实验装置,对散射参数(Scattering Parameters)进行测量,经高频电磁仿真软件(CST)仿真,验证实验结论。在3.50 GHz和4.86 GHz这2个频率点,入射波的吸收率能够超过90%,可较好实现硅基橡胶聚合物基复合吸波材料对5G射频天线干扰的抑制作用。
Under the construction of 5G network,the electromagnetic environment becomes increasingly complex and the electromagnetic interference phenomenon becomes increasingly serious.The application scenarios and characteristics of 5G MU-MIMO large-scale antenna array are analyzed,and the electrophysical properties of absorbing materials are also explored.Methyl silicone rubber is used as the raw material of the absorber unit structure to meet the requirements of outdoor use of 5G antenna.The technical route and absorber material,shape,size and other parameters are designed,and the waveguide experimental device is set,Scattering Parameters are measured,and the simulation results are verified by high frequency electromagnetic simulation software(CST).At the frequency points of 3.50 GHz and 4.86 GHz,the absorption rate of incident waves is greater than 90%,which can better realize the suppression effect of silicon rubber polymer based composite absorbing material on 5G RF antenna interference.
