Description
周知の、従来のセルラー式無線受信機の回路を有する携帯無線電話を具体化したもので、本発明では簡単化のために説明しない。携帯電話は、小型の筐体中で集積化されたユーザーインタフェイスのような、従来のセルラー式電話のハードウェア(これも、簡単化のために説明しない)で構成されており、さらに、本発明によるアンテナ装置も含まれる。個
々の通信装置は、この概念と、それぞれの応用のために選択される方法を実現する。
対称性デルタ整合導体107とベントダイポール105の先端部は第2の周波数で動作するループアンテナを形成する。アンテナ112は平衡伝送線路106による給電点110で給電される。アンテナの構成は、フリップ102の縦中心軸に関して完全に対称である。アンテナ構成の対称性は、平衡給電伝送線路106の使用と同時に、アンテナ制御のモード平衡という役割も担っている。
ましくは、ダイポールは900MHzに調整され、その全長は動作周波数の1/2波長近傍である。
合導体によって接点で効率的に動かされている。任意で、1組の導電性アーム109は接点108に近接するデルタ整合導体107に接続され、同様に駆動される。好ましくは、これらの導電性アーム109は、第2の周波数帯もしくはその近傍で共振し、その周波数帯を調整するのに使われる。この場合、両導電性アーム109の長さは、高い周波数帯での周波数を調整するように選択される。有効な長さは他の構成要素との電磁結合によって変化する。さらに、物理的長さは、当技術分野で周知のような材料添加の加減によって最適化することにより変化する。あるいは、導電性アーム109は多周波数帯で動作させるために、第1、第2の周波数とは異なる、第3の周波数における共振を提供できるように選択し得る。追加した1組の導電性アームは、第3あるいはそれ以上の周波数で、多周波数帯での動作をするために同様の方法でアンテナ装置に取り付けられる。言い換えると、第1、第2の周波数とは異なる第3の、あるいは、それ以上の周波数である。
