Design of an UHF RFID tag antenna for paper money management system

In this paper, an UHF dipole tag antenna with a short stub and meander lines is proposed for RFID-based paper money management system. The short stub and meander lines in tag antenna are used to improve the impedance matching between tag antenna and tag IC. The proposed RFID tag antenna can be used effectively to band wads of paper money at banks and financial agencies for security purpose.
