Dielectric shielding for improved RF performance of RFID

摘要

The RFID label or tag with dielectric shielding to insulate the RFID integrated circuit and antenna from the target surface which the device may be in contact. Dielectric shielding may be formed from the liner, cut so that when the liner is peeled off the section between the transponder and the target surface remains. The liner may be arranged so that the portion covering the RFID transponder cannot be removed accidentally through use of a zone not coated with release agent. Dielectric shielding may be formed from a portion of the face sheet. The face sheet will be configured to allow it to be folded upon itself to provide insulation between the RFID transponder and the target surface. Adhesive applied to the face sheet may be used to create an adhesive surface for attaching a RFID label to a target surface.
