Abstract

La présente invention concerne un dispositif (3) de détection d'approche d'un équipement (S) électronique portable et de communication en champ proche avec une première antenne (1) de communication à haute fréquence et une unité de contrôle et d'alimentation électrique présentant des moyens de mesure d'une variation d'amplitude d'un paramètre électrique représentative d'une détection d'approche de l'équipement (S). Le dispositif comprend une deuxième antenne (2) de communication en champ proche logée dans un espace délimité par la première antenne (1) et associée à des moyens de résonance en étant reliée à l'unité de contrôle par un interrupteur (9) présentant une première position pour une communication en champ proche où la deuxième antenne (2) n'est pas alimentée et une deuxième position pour une détection d'approche où la deuxième antenne (2) est connectée et entre en résonance avec la première antenne (1) active.
