Abstract :
Three different UHF RFID tag antennas are designed and fabricated. The reading ranges of tags are 1.7m, 1.9m and 0.85m. The first tag antenna used the transmission line, and the second tag antenna used a shorted patch antenna. The third antenna used the transmission line and L shape patch antenna to match the impedance of the tag antenna to the conjugate of chip impedance.
