Abstract
This paper describes a design method of a metasurface that consists of two types FSS (Frequency Selective Surface) and the ground plane to realize broadband reflected wave reduction. The ideal filtering characteristics of one FSS is clarified when the other FSS is a patch type FSS. A loop and patch type FSS is proposed to realize the ideal filtering characteristics. Then, a meta-surface with reflected wave reduction function is constructed with the patch type FSS and the proposed FSS. As a result, 48.9 % of a relative bandwidth within a reflection amplitude −10 dB or less is obtained by the proposed meta-surface.
