Title (EN) MODULAR RFID ANTENNA SYSTEM
(FR) SYSTEME D'ANTENNE RFID MODULAIRE
Abstract:
(EN) A modular radio frequency (Fig. 9) identification device (RFID) antenna system (S1) including a plurality of modular RFID antenna segments (10a-10d) that can be connected in multiple configurations to allow multi-directional RF communication with at least one RF tag (5) that passes through the field of the antenna system from different directions and at different orientations and a configurations system to design, order, configure, test and operate the modular RFID antenna system.
(FR) L'invention concerne un système d'antenne (S1) à dispositif d'identification modulaire haute fréquence (RFID) (Fig. 9), qui comprend une pluralité de segments (10a-10d) d'antenne RFID modulaires pouvant être connectés dans de multiples configurations pour permettre d'établir des communications multidirectionnelles RF avec au moins une étiquette (5) électronique RF traversant le champ du système d'antenne à partir de différentes directions et dans différentes orientations ; et un système de configuration permettant de concevoir, d'ordonner, de configurer, de tester et d'exploiter ce système d'antenne modulaire RFID.
