Abstract

マイクロストリップアンテナを用いたリアクタンス変化による可変指向性アンテナにおいて，素子間隔を小さくした際に生じるサイドローブを低減する構成であって，給電素子と，前記給電素子の両側に配置された無給電素子を有する３素子平面構成の可変指向性アンテナにおいて，前記給電素子の両側に配置された無給電素子のそれぞれは，横方向に１：２の大きさに２分割された２つの分割無給電素子を有し， 前記１の大きさに分割された分割無給電素子が，前記給電素子に近い側に配置され，前記２の大きさに分割された分割無給電素子にリアクタンス可変部が接続されている。あるいは，前記給電素子の両側に配置された無給電素子のそれぞれは，横方向に２：１の大きさに２分割された２つの分割無給電素子を有し，前記２の大きさに分割された分割無給電素子が，前記給電素子に近い側に配置され，前記２の大きさに分割された分割無給電素子又は，前記１の大きさに分割された分割無給電素子のいずれか一方にリアクタンス可変部が接続されている。
