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.
