- In this paper, the design of a long read range UHF RFID tag was presented. The read range is one of the key parameters in RFID systems and is frequently evaluated for RFID system assessment. Conventional tag designs were generally focused in saving power consumption, which results in the degradation of the tag sensitivity and a shorter read range. A battery-assisted passive tag provides a better sensitivity in forward-link and the amplification of backscattering signal provides a longer read range in reverse-link. The minimum threshold power of the designed tag was measured to be -23dBm and the amplification of the backscattering signal by 28 dB provided the twice read range of the conventional passive tag, which was predicted by simulation. © 2009 EuMA.
