摘　　要：分析交叉振子平面反射阵列天线的移相特性和传输特性,针对FFS地板和交叉振子构成双层结构的阵列天线,采用整体建模并利用Floquent方法数值分析了其移相与传输特性。结果表明,相比单层结构分析方法,该实验结果更加准确,有助于反射阵列天线的精确设计。The reflection phase and transmission property of reflectarray antenna with crossed dipoles are discussed in this paper. The model of reflectarray antenna backed either by a solid metal ground plane or a frequency - selective surface is .built integrally with Floquet ports. The reflection phase and transmission property between two configurations is analyzed. Compared to the traditional method,integrated building methods present in this paper is more accurate in the precise design of reflectarray antenna.
