We investigate how realistic architecture considerations affect the performance of wafer-scale electronically scanned millimeter-wave reflectarrays. Considering the application of a confocal Gregorian optics geometry with a small angular field of view, we examine how a reflectarray's discrete (digital) phase state quantization and electrical size impact scan angle accuracy and quantization lobe performance degradation. We quantify the impact of these effects on the camera's imaging performance and show that, for these reflectarrays, phase quantization of 2 bits is sufficient.
