为解决毫米波信道反射和透射特性测量数据不足、多层材料传播系数计算不准确和传播特性表征不明的问题,该文开展面向6G通信感知一体化(ISAC)的40~50 GHz毫米波信道反射和透射特性研究.首先,基于菲涅尔理论和射线弹跳追踪原理,提出一种室内多层建筑材料传播系数计算方法;然后,利用基于矢量网络分析仪的毫米波信道测量平台,开展40~50 GHz频率范围内多层木板和多层玻璃的反射和透射系数测量活动.结果表明,该方法与测量值间高度吻合,传播系数误差低于0.1,能够准确地刻画毫米波信道反射和透射特性变化规律.此外,研究还发现反射系数谐振特性和有效布儒斯特角特性依赖于电波极化、入射角和材料厚度.
Research on Reflection and Transmission Characteristics of the Millimeter Wave Channel at 40~50 GHz for 6G ISAC
Considering the insufficient measurements for reflection and transmission characteristics of millimeter-wave channel and inaccurate calculation methods for propagation coefficients of multilayer building materials,an extensive investigation on the reflection and transmission characteristics of millimeter-wave channel at 40-50 GHz is conducted for 6G Integrated Sensing And Communications(ISAC).Firstly,a method for calculating propagation coefficients of multilayer building materials is proposed based on Fresnel theory and shooting and bouncing ray principle.Furthermore,extensive measurement campaigns at 40-50 GHz are carried out to obtain reflection and transmission coefficients of multilayer wood and glass using VNA-based millimeter-wave channel sounder.The results show that the measured values are in good agreement with the theoretical values and the propagation coefficient error is less than 0.1,which verify the accuracy and effectiveness of the proposed method.Besides,it is also found that the resonant period and effective brewster angle of reflection coefficient are dependent on polarization,incident angle,and material thickness.
