Abstract
Description
本発明は、平面アンテナ又はその改良物に関し、特に、それに限るわけではないが、携帯電話に用いられるアンテナに関する。このような電話はGSM及びDCS1800標準規格に従って動作する。
図1に示すように典型的なデュアルバンドPIFAは、グラウンドプレーンを含む電話機プリント回路基板(PCB)PPにフィードタブ(又はピン)FT及び短絡タブ(又はピン)STを介して接続され、放射素子REを備える。放射素子REはまたほぼU型のスロットSOを含む。このようなアンテナは特に特許文献US2001/0035843に記載されている。
本発明は、通常はより大きい1つのアンテナにより占有されている携帯電話機内のスペースに2つの小さいMEMS切り替えPIFAアンテナを実装することを提案する。このようなデュアルMEMS切り替えPIFAアンテナは図7に示される。
Claims (8)
