Abstract
【解決手段】例示的実施形態は無線電力伝達を対象にする。送信器(202)は、送信アンテナ(204)を使用して、共振周波数で送信アンテナの近接場内に結合モード領域を生成するように電磁場を生成する。この送信器は、電磁場をオンオフキーイングすることにより、繰返し期間の始めを、繰返し期間の同期部分を通じて定義する。この送信器は、繰返し期間の送電部分を通じて、電磁場の一部分を、結合モード領域内の様々な受信器デバイスの別々の受信アンテナに結合する。この送信器は、また、結合モード領域内に配置された様々な受信器デバイスに対する繰返し期間内の電力割当てを求めて、受信器デバイスから受け取られた電力要求に応じて近接場放射の電力レベルを調節する。
