摘要
Slot radio frequency identification (RFID) Tag antennas designed for ultra-high frequency (UHF) band are presented. Two orthogonal slots are used to achieve circular polarization (CP). By selecting an appropriate length of feed-lines, the input impedance of the tag antenna can be controlled. Experimental results show a good reading range between 9 m and 10 m. A wide band CP band was measured. The design procedure for the proposed antennas are described and the performances are presented and discussed.
