Abstract

Antenne (2) electronique de type « boucle » pour I'identification radiofrequence dans un volume de detection (V), comprenant au moins deux portions de fil conducteur (3), et au moins un boÊtier d'interconnexion (4) dispose entre les portions de fil (3), comprenant au moins un condensateur de capacite variable. Chaque boÊtier comprend des moyens de commande de Ia valeur de Ia capacite du condensateur. L'antenne comprend egalement : - des moyens (5) d'affectation a chaque boÊtier d'interconnexion (4) d'une valeur de capacite pour Ie condensateur communiquant avec les moyens de commande de Ia valeur de Ia capacite du condensateur, et - un lecteur (12), associe aux moyens d'affectation (5), comportant des moyens d'analyse (33) qui determinent, en faisant varier les valeurs de capacite de I'au moins un condensateur, lesdites valeurs pour lesquelles une qualite donnee de signaux detectes, provenant notamment d'au moins une etiquette radiofrequence situee dans Ie volume de detection (V), est obtenue.
