Abstract
A reflectarray antenna consists of the elements of double-layer rectangular patches with slot loading of different lengths, printed on the upper- and down-surfaces of a single- layer substrate respectively, and suspended over a ground plate is proposed and designed for bandwidth enhancement. It has 15% bandwidth for -1 dB gain-drop from the peak value, is obviously wider than that of conventional reflectarray.
