摘要：

A reflectarry antenna composed of double square rings of variable lengths printed on a conductor-backed substrated is proposed for enhancement. Using this technique, a single-layer reflectarray of a wider bandwidth compared to conventional single-layer reflectarrays is designed, fabricated, and measured. The measured results demonstrate a radiation efficiency close to 52% and 1-dB gain bandAvidth of 9%, centered at 22 GHz. (c) 2006 Government of Canada.
