Abstract
La présente invention concerne un système de capteur sans fil comprenant un circuit de détection et un détecteur. Le circuit de détection comprend une source de signal connectée à une antenne. Un matériau détecté à proximité de l'antenne induit un changement de l'impédance de l'antenne, conduisant à un changement de la fréquence de fonctionnement du circuit de détection. Le changement de la fréquence de fonctionnement est détecté par un détecteur, tel qu'un comparateur. Lorsque le circuit de détection et le détecteur sont tous deux inclus dans un émetteur du système de capteur sans fil, une sortie du détecteur peut être combinée au signal émis par l'antenne. Lorsque le signal est reçu au niveau du récepteur, la sortie du détecteur peut être décodée et utilisée pour déterminer une propriété du matériau détecté. Le signal peut comprendre d'autres données, telles que des données pilotes, générées au niveau de l'émetteur. Selon un autre mode de réalisation, le détecteur est situé au niveau du récepteur.
