Abstract

　アレーアンテナにおいて、給電する素子数を削減し、その結果、給電回路を簡略化する。特に、自由空間に配置したアレーアンテナでなく、アレーアンテナに近接した反射板が存在する場合に、給電素子を間引きする。 　複数の放射素子と、反射板を備え、複数の放射素子が反射板の反射面と略平行な同一平面上に配置されているアレーアンテナであって、複数の放射素子は、給電端に給電線が接続された給電素子と、給電端を短絡又は開放させた無給電素子を含み、給電素子を挟む位置に無給電素子が配置され、給電素子のサイドローブによって照射された無給電素子による再放射波の位相が、複数の放射素子の各々から放射される放射波の位相と同一位相であるアレーアンテナ。
