RFID devices having self-compensating antennas and conductive shields
Abstract:
A radio frequency identification (RFID) tag includes an antenna configuration coupled to an RFID chip, such as in an RFID strap. The antenna configuration is mounted on one face (major surface) of a dielectric material, and includes compensation elements to compensate at least to some extent for various types of dielectric material upon which the antenna configuration may be mounted. In addition, a conductive structure, such as a ground plane or other layer of conductive material, may be placed on a second major surface of the dielectric layer, on an opposite side of the dielectric layer from the antenna structure.
