Design of secure UHF RFID tag by binding object dielectric permittivity

• Antennas can always be affected by the attached materials. Such a property is here integrated with RFID technology of designing a passive RFID tag which is sensitive to a chosen object material. A good sensing ability will help the tag bonding up with the chosen material, which will benefit material security a lot. To achieve a high tag-object bonding sensitivity, a fragmented-type tag is introduced here. When permittivity of attached object material changes a little bit, readability of the tag will degrade rapidly. The sensitive properties are investigated by simulated and articulated experimentations.
