A multi-loop antenna is described having a plurality of conductive loops to produce an electromagnetic field for radio frequency identification (RFID) communication with RFID tags. The conductive loops are spaced apart at least a distance that is selected based on a dimension of the RFID tags with which the antenna communicates. In this manner, the loops are positioned and spaced in a manner that reduces the size of the holes within the resulting magnetic field. In addition, the configuration of the described dual-loop antenna increases the coverage of the antenna, and decreases inter-winding capacitance, thereby increasing overall read range achieved by the antenna.
L'invention porte sur une antenne à plusieurs boucles de communication de l'identification de fréquences RF (RFID) au moyen de marqueurs RFID. Les boucles conductrices sont séparées d'une distance sélectionnée sur la base des marqueurs RFID avec lesquels elle communique. Les boucles sont disposées et espacées de manière à réduire la taille des trous dans le champ magnétique résultant. De plus, la configuration de l'antenne à deux boucles accroît sa couverture, diminue la capacité inter-enroulements, d'où un accroissement de sa portée totale de lecture.
