Abstract

各種システムに対応した多数のアンテナ部を近接させて狭い領域に実装しても干渉が生じず、しかも小型化と低コスト化が可能なアンテナ装置及び無線通信機を提供する。 アンテナ装置１は、１つの誘電体基体２に実装したアンテナ部３～５を備える。基本周波数の最も低いアンテナ部３を非グランド領域１０１の左端部に配置し、アンテナ部３の高調波の周波数に最も近い基本周波数を有したアンテナ部４を右端部に配置し、アンテナ部３の周波数とアンテナ部４の周波数との間の基本周波数を有したアンテナ部５をアンテナ部３，４間に配設した。そして、電流密度制御コイル６をアンテナ部３の放射電極３１と給電部３０との間に接続し、リアクタンス回路７を放射電極３１の途中に介設した。好ましくは、切り欠き部２０を、放射電極３１と放射電極４１との間、及び放射電極３１と放射電極５１との間に設ける。
