Gain and Bandwidth Limitations of Reflectarrays

摘要

In reflectarray antenna designs, it is important to find the gain and bandwidth for a desired application. In this paper, two analysis methods are illustrated, which can provide quick estimations on the reflectarray gain and bandwidth. A quantitative comparison on these two different approaches is made in terms of accuracy and computation time. Parametric studies are performed to provide design guidelines for selecting appropriate f/D ratio and feed pattern of a center-fed reflectarray in order to optimize the antenna gain and bandwidth. A gain and bandwidth comparison between the broadside and offset fed reflectarray antennas is presented. Furthermore, the effect of element bandwidth on the performance of an X-band reflectarray is given both numerically and experimentally.
