Abstract: front page image
(EN)The invention concerns a loop-type electronic antenna (2) for identifying radio frequency in a detecting volume (V), comprising at least two conductor wire portions (3) and at least one interconnection box (4) arranged between the wire portions (3), including at least one variable capacitance capacitor. Each box comprises means for controlling the value of the capacitance of the capacitor. The antenna further comprises: means (5) for allocating to each interconnection box (4) a capacitance value for the capacitor communicating with the means controlling the value of the capacitance of the capacitor, and a reader (12), associated with the allocating means (5), comprising analyzing means (33) which determine, by varying the capacitance values of at least one capacitor, said values for which a given quality of detected signals, from in particular at least one radio frequency label located in the detection volume (V), is obtained.
(FR)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.
