Abstract

A reflectarray having multiple elements arranged in an array, each element having a H-shaped patch provided in separation from a ground plate, the H-shaped patch formed by four outer vertices defined by two rectangular outer patches and four inner vertices defined by an inner patch. A length of the inner patch with respect to a first direction is determined to change the reflection phase of an electric field incoming in parallel to the first direction while keeping positions of the four outer vertices and sizes of the outer patches constant. The first direction is determined by positions of the four inner vertices, and a length of the H-shaped patch with respect to a second direction is determined to change the reflection phase of an electric field incoming in parallel to the second direction, wherein the second direction is determined by positions of the four outer vertices.
