A reflectarray antenna composed of double square rings of variable lengths printed on a conductor‐backed substrate is proposed for reflectarray‐bandwidth 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 bandwidth of 9%, centered at 22 GHz. © 2006 Government of Canada.
