Abstract
A reflect array includes a patch electrode, a ground electrode arranged opposite the patch electrode and spaced apart from the patch electrode, a liquid crystal layer between the patch electrode and the ground electrode, and a dielectric substrate on an opposite side of the patch electrode from the liquid crystal layer. A thickness T from a surface on the liquid crystal layer side of the patch electrode to a surface on the opposite side of the dielectric substrate from the patch electrode has a thickness equivalent to a quarter of the wavelength of the radio wave irradiated to the patch electrode.
