Abstract
For cigarette identification with UHF RFID technique, passive UHF RFID tag must be attached to the pack or carton. Due to the aluminum foil in the package and very limited thickness of the package, the UHF tag has to operate in very close proximity to metallic surface. In this paper, we report a design of passive UHF RFID tag on a cigarette pack, which is challenging because of the small pack size and proximity to metal. Several design considerations are introduced and a prototype UHF tag on cigarette pack is fabricated and tested. A maximum read range of approximately 3m is measured in lab environment by using a UHF reader of 4W ERIP at 915MHz.KeywordsRadio frequency identification (RFID)antenna tagcigarette pack
