摘要：

In this paper, the effects of large angle of incidence in offset-fed reflectarray antennas using the single-layer ring is presented. When the incidence angle becomes large, the reflection phase of the ring becomes highly frequency dispersive. As a result, the normal-incidence reflection phase curve is no longer valid for designing the element to compensate the spatial phase delay. The phase error will shift the reflected beam direction and reduce the antenna gain.
