Abstract
In this paper, performance degradation of RFID system due to curving in tag antenna is investigated through radar cross section (RCS) analysis. While the limitation in the read range of passive RFID system is mainly dominated by the received RF power from reader on the tag side, RCS analysis of tag antenna provides a direct and effective way for the evaluation of overall system performance. For simplicity consideration without losing generality, a simple half-wavelength planar dipole at 900MHz is used for RCS analysis under various curving conditions. Results show that the read range can be degraded significantly due to curving.
