Abstract
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.
