A Novel Design of UHF RFID Passive Tag Antenna Targeting Smart Cards Limited Area

摘要

The aim of this paper is to design an Ultra High Frequency (UHF) Radio Frequency Identification (RFID) passive tag antenna to fit in the limited space of smart cards, such as bankcards, along with contactless payment facility and Europay, MasterCard and Visa (EMV) chip. In this paper, UHF tag antenna is designed using Monza R6 chip specifications from Impinj manufacturers while focusing on high performance and read ranges of upto 12 meters with very small sized antenna dimensions of 17:9 x 47:30 mm2 . Performance is analysed in terms of gain, read ranges and power reflection coefficients. UHF tag antenna is designed using aluminium on Polyethylene Terephthalate (PET) substrate. The proposed design aims to meet objectives of low cost and small size while maintaining high performance.
