Abstract

Ausführungsbeispiele der vorliegenden Erfindung schaffen eine Vorrichtung, mit folgenden Merkmalen: einer magnetischen Antenne, wobei die magnetische Antenne eine einfach oder mehrfach unterbrochene Schleife und zumindest ein Abstimmelement zur Abstimmung der magnetischen Antenne aufweist; und einer Abstimmeinrichtung, wobei die Abstimmeinrichtung eine Regelschleife aufweist, die konfiguriert ist, um ein Abstimmsignal zur Abstimmung der magnetischen Antenne bereitzustellen, und um das Abstimmelement mit dem Abstimmsignal anzusteuern, um die magnetische Antenne abzustimmen, wobei die Vorrichtung konfiguriert ist, um die Regelschleife oder eine Komponente der Regelschleife nur bei Bedarf von einem Ruhemodus in einen normalen Betriebsmodus zu versetzen.
