本文详细概述了波束扫描反射阵列天线的各种设计方法和实现技术。描述了反射阵列相对于反射器和相控阵的许多优点，并回顾了代表性的波束扫描反射阵列天线设计。对于有限视场波束扫描系统，利用反射阵列天线的反射器特性和馈电调谐技术可以提供具有良好性能的简单解决方案。另一方面，对于需要广角扫描覆盖的应用，利用反射阵列的阵列性质和孔径相位调谐方法是更合适的选择。这两种设计方法都有多种支持技术，使它们成为新一代高速、高增益波束扫描天线的合适选择。
A detailed overview of various design methodologies and enabling technologies for beam-scanning reflectarray antennas is presented in this article. Numerous advantages of reflectarrays over reflectors and phased arrays are delineated, and representative beam-scanning reflectarray antenna designs are reviewed. For limited field-of-view beam-scanning systems, utilizing the reflector nature of the reflectarray antenna and the feed-tuning technique can provide a simple solution with good performance. On the other hand, for applications where wideangle scan coverage is required, utilizing the array nature of the reflectarray and the aperture phase-tuning approach are the more suitable choices. There are various enabling technologies available for both design methodologies, making them a suitable choice for the new generation of high-speed, high-gain beam-scanning antennas.
