REFLECTARRAY AND DESIGN METHOD

摘要

A reflectarray reflects an incident wave in a desired direction. The reflectarray includes a substrate including a surface which is perpendicular to a predetermined axis, and elements disposed on the substrate. A specific element among the elements reflects the incident wave with a specific reflection phase among a plurality of reflection phases. Each of the elements has an element structure including, at least, a patch and a ground plate. Element spacing of first neighboring elements is different from element spacing of second neighboring elements, and a length of a gap between patches of the first neighboring elements is equal to a length of a gap between patches of the second neighboring elements.

1. A reflectarray that reflects 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 reflects the incident wave with a specific reflection phase among a plurality of reflection phases, wherein each of the elements has an element structure, wherein the element structure includes, at least, a patch and a ground plate, wherein element spacing of first neighboring elements is different from element spacing of second neighboring elements, and wherein a length of a gap between patches of the first neighboring elements is equal to a length of a gap between patches of the second neighboring elements.
