本文研究了用PIN二极管实现的1位可重构反射阵列天线（RRA）的波束扫描性能。结果表明，通过优化补偿相位，可以有效地改善1比特量化带来的性能恶化。进一步分析了3种不同孔径尺寸的RRA的性能，结果表明，随着孔径尺寸的增大，波束指向误差和峰值旁瓣电平均减小，而量化损耗增大缓慢。
This paper investigates the beam-scanning performance of 1-bit reconfigurable reflectarray antennas (RRA) implemented with PIN diodes. It is found that the performance deterioration resulted from 1-bit quantization can be alleviated by the optimization of the compensation phases. Furthermore, the performance of three RRAs with different aperture sizes are analyzed, and the results show that with the increase of aperture size, both the beam point error and peak sidelobe level decrease, while the quantization loss increases slowly.
