Claim Text:
1. A reflectarray configured to reflect an incident wave in a desired direction, the reflectarray comprising: a substrate that includes a surface which is perpendicular to a predetermined axis; and a plurality of elements disposed on the substrate, wherein a specific element among the elements is configured to reflect the incident wave with a specific reflection phase among a plurality of reflection phases, wherein each of the elements has a mushroom-like structure, wherein the mushroom-like structure includes a patch, a gap between the patch and the ground plate, and a via hole, wherein element spacing between neighboring elements among the elements is a distance between the via holes of the neighboring elements, wherein the element spacing of first neighboring elements among the elements is different from the element spacing of second neighboring elements among the elements, and a length of a gap between the patches of the first neighboring elements is equal to a length of a gap between the patches of the second neighboring elements, wherein the element spacing is variable, and wherein the mushroom-like structures are configured so that the gaps among the patches of the mushroom-like structures can be simultaneously changed by a same value, so as to change the reflection phases.
