UHF RFID Tag for Integration Into a Cigarette Pack

Passive UHF radio frequency identification (RFID) tag is proposed for integration into a cigarette pack. The UHF tag is designed on 0.5-mm-thick paper on aluminum foil. Effects of some key structures of the tag on impedance matching are analyzed. A prototype of the proposed tag is fabricated and tested, and a maximum read range of approximately 3 m is measured in a lab environment by using a UHF reader of 4 W EIRP at 915 MHz. By introducing an additional slot and auxiliary pull-tab strip to increase impedance tuning range, the proposed tag structure can be used to match different RFID chips on packages of different metallic objects .
