REFLECTARRAY

摘要

A reflectarray is formed by arranging a plurality of mushroom structures on a bottom board. Each of the mushroom structures comprises one quadrilateral patch and a via for short-circuiting the patch and the bottom board. Adjacent vias are arranged so as to be equally spaced in both the horizontal and vertical directions of the bottom board. The space dimension between adjacent patches is adjusted so that the value of the reflection phase of the reflected wave from the patches becomes a desired value.
