毫米波频段人体电波传播特性综述

A review for radio wave propagation characteristics on human body in millimeter wave band

毫米波频段可提供数GHz的频谱,成为第5代无线蜂窝网络极具吸引力的选择。其目前测试场景往往不能忽略人体的存在。文中详细介绍了电波传播的信道建模方法、测试环境和仿真模型。在测试环境和方法中主要讲述了人体模型的建立和天线的类型、位置等。并介绍了基于入射反弹法(SBR)和时域有限差分法(FDTD)两种仿真模型。最后对人体阻挡影响、散射特性、基站方位影响等性能进行了分析。

Millimeter wave(mm W) band can provide several GHz,it becomes an attractive option for the fifth generation wireless cellular network. At present,the test scene often cannot ignore human body(HB) existence. In this paper,it introduces channel modeling method in mm W band,test environment and simulation model. In the test environment and method,it mainly gives account of HB modeling and antenna type,position etc. In simulation modeling,mainly introduces two style modeling of SBR and finite difference time domain method(FDTD). Finally,it analyzes the impact of the human body blockage,scatter,base station azimuth and other performance.
