More Information
Summary:A passive radio frequency identification (RFID) reader is configured to dynamically vary the Q factor of its resonant antenna coil circuit in order to optimize its performance under different conditions. This RFID reader suitably provides optimal performance for both transponder reading and transponder writing operations, rather than being designed for optimal performance for only one operation or the other, or some fixed compromise between them. Un lecteur d'identification par radiofréquence (RFID) passif est configuré pour faire varier dynamiquement le facteur Q de son circuit de bobine d'antenne résonante afin d'optimiser ses performances dans différentes conditions. Ce lecteur RFID fournit de manière appropriée des performances optimales à la fois pour les opérations de lecture de transpondeur et d'écriture de transpondeur, plutôt que d'être conçu pour des performances optimales pour une seule opération, ou un certain compromis fixe entre celles-ci.
