在移动广播与通信领域,电磁波经过瑞利信道传播到达接收地点,多径传播的合成与光的偏振现象具有相似的特性,在光学理论中,庞加莱球面主要用来分析光的偏振现象。本文深入分析了U波段电磁波多径传播的极化特性,介绍了电波与天线的极化参数在庞加莱球面的表达方法,对极化匹配效率的计算问题进行了论证,以期为移动终端天线设计提供一种完备的理论工具。
In the field of mobile broadcasting and telecommunications, the propagation of electromagnetic waves through the Rayleigh channel reaches the receiving location. The combination of multipath propagation and the polarization of light have similar characteristics. In optical theory, the Poincaré sphere is mainly used to analyze the polarization of light. In this paper, the polarization characteristics of U-band electromagnetic multipath propagation are analyzed in detail. The method to express the polarization parameters of the electromagnetic wave and the antenna in the Poincaré sphere is introduced. The calculation of the polarization matching efficiency is demonstrated. Design provides a complete theoretical tool.
