摘要
室内无线电通信的研究必须要知道室内建筑材料的电参数,对内装金属丝的强化玻璃、塑料板墙和木制门等常见室内建筑材料在5.8GHz的反射系数、透射系数和介电常数进行了测量和理论计算。测量结果和理论计算结果非常一致。在对测量结果处理时,使用了时间门限(TimeGating)技术来消除周围环境的影响。
To study wireless communication in door, it is essential to know the permittivity of common materials in door. The reflection and transmission coefficients of wire glass, wooden door and plaster-board were measured and calculated. The measured results are good agreement with that calculated. The time-gating technology is applied to eliminate the influences of environments.
