Abstract
In this paper, we have designed a RFID reader receiver system for improving the performance of the passive Tag based 908.5-914 MHz RFID reader, and analyzed the system performance vis-à-vis frequency, reader, and tag properties. The commercial receiver system causes a loss in sensitivity because of its 24 capacitors and 6 inductors. To improve the overall sensitivity of the receiver, we have designed a system using a circulator, LNA and a SAW filter. The experimental results show that the use of a circulator to separate the Tx/Rx paths eliminates interference, the LNA improves the sensitivity of the Rx module and SAW filter eliminates the noise and spurious components in the received signal. © Springer-Verlag Berlin Heidelberg 2007.
