Abstract :
A novel reflectarray antenna using a new class of cell elements labelled `sub-wavelength coupled-resonant elements` is presented to enhance phase variation that avoids the tight fabrication tolerances needed in the fabrication of conventional reflectarrays comprised of sub-wavelength coupled-resonant patch elements.
