Abstract

　基本モードと高次モードの共振周波数を別々に独立に制御することができ、しかも、基本モードの共振周波数の可変幅が広いアンテナ装置及び無線通信機を提供する。 　給電電極２とループ状放射電極３と容量部４とインダクタ５，６とを備える。容量部４はループ状放射電極３の開放端３ａと給電電極２との間隙で形成し、インダクタ５は基本モードの電流が大きく且つ高次モードの電流が小さい部位に配設し、インダクタ６は高次モードの電流が大きく且つ基本モードの電流が小さな部位に配設した。基本モード時の電流が給電電極２からループ状放射電極３に流れ、開放端３ａの容量部４で阻止される。高次モードの電流は給電電極２から容量部４を通じてループ状放射電極３の開放端３ａ側に流れ、インダクタ５で阻止される。好ましくは、容量可変素子７をインダクタ５に接続する。
