Selon l'invention, l'effort nécessaire est réduit lorsqu'un utilisateur accède à un récepteur qui est alimenté en électricité par alimentation sans fil, et qui possède un capteur destiné à capter l'état d'un dispositif prédéfini sur lequel il est installé. Plus précisément, le récepteur de l'invention est équipé d'une antenne, d'un circuit, d'une interface et du capteur. L'antenne est à son tour équipée d'un premier conducteur, et d'un second conducteur prenant une forme circulaire avec le premier conducteur par connexion avec celui-ci. Le circuit est installé dans une première zone d'un substrat sur lequel est formé le premier conducteur. L'interface est connectée au circuit, et est installée sur une face de direction extérieure de la forme circulaire au niveau de l'antenne. Le capteur est également connecté au circuit, et est également installée sur une face de direction extérieure de la forme circulaire au niveau de l'antenne.
