摘　　要：为解决圆极化反射阵带宽窄的问题,从单元的角度出发,首先推导了旋转单元角度实现相位补偿的基本条件,然后计算了反射阵阵面相位分布,结合线极化反射阵单层多谐振思想,提出了一种"双环"形宽带圆极化反射阵单元。设计了一副13×13个单元、中心频率为10GHz的偏馈右旋圆极化反射阵:3dB轴比带宽达到43%(8.1GHz～12.4GHz),口径效率最高达58.55%(9.8GHz)。In order to solve the problem of narrow bandwith for circularly polarized reflect-array,the requirement for an element to realize phase compensation is first derived by using angular rotation techniques, and the surface phase distribution of the reflect-array is calculated. Based on the idea of single-layer multiple-resonance structure,this paper proposes a double-ring shaped broadband circu- larly polarized reflect-array element. A CP reflect-array using element rotation techniques has been designed and measured,the 3dB axial ratio bandwith is over 43% ,and the aperture efficiency can reach as large as 58.55%
