本文比较了分析反射阵天线辐射性能的两种基本方法。两种不同的方法-阵列理论和孔径场-首先描述，然后给出了各种反射阵列配置的数值结果。每种方法的优点和局限性进行了讨论，数值结果相互比较，显示出很好的协议。与全波仿真结果的比较表明，这些方法是时间有效的方法，可以准确地计算反射阵列天线的方向图形状，主波束方向，波束宽度，旁瓣和交叉极化水平。因此，这些方法可以为天线工程师设计和分析反射阵列天线提供有效的工具。
This paper compares two basic methods for analysis of the radiation performance of reflectarray antennas. Two different approaches - array theory and aperture field - are first described, and numerical results are then presented for various reflectarray configurations. The advantages and limitations for each method are discussed, and the numerical results are compared with each other, showing very good agreement. Comparison with full-wave simulations showed that these approaches are time-efficient methods that can accurately calculate the reflectarray antenna's pattern shape, main-beam direction, beamwidth, and sidelobe and cross-polarization levels. As such, these methods can be efficient tools for antenna engineers for designing and analyzing reflectarray antennas.
