Abstract

La présente invention a pour objet un capteur (1) de détection de la présence d'un équipement d'utilisateur par communication en champ proche pour véhicule automobile, ledit capteur (1) comprenant une antenne (50), un adaptateur (40) d'impédance, un module de pilotage (20) de l'antenne (50), et un microcontrôleur (50), configuré pour commander ledit module de pilotage (20), ledit adaptateur (40) d'impédance étant apte à adapter l'impédance de sortie du module de pilotage (20) à l'impédance de l'antenne (50) tout en amplifiant la puissance fournie par ledit module de pilotage (20). Le capteur (1) comprend un module résistif (30), monté entre le module de pilotage (20) et l'adaptateur (40) d'impédance, configurée pour stabiliser la valeur de la puissance d'entrée de l'adaptateur (40) d'impédance.
