Reflect array, design method for reflect array, and reflect array system

Abstract

The present invention addresses the problem of high costs resulting from the necessity of a variety of reflector design parameters due to area size and distance of transmission/reception and reflectors. A design method for a reflect array that transmits, to a reception region, radio waves from a base station used in communications, said method comprising: a gain setting step for setting necessary gain; a width setting step for setting a necessary beam width; a preparation step for preparing a plurality of reflectors having differing reflection directions from each other; and an arrangement step for arranging the plurality of reflector such that the beams formed by the plurality of reflectors satisfy the necessary beam width as a whole.
