Abstract :
Readability is a very important factor for radio frequency identification (RFID) applications. One of the main reasons for readability degradation is field nulls (also called dead zones). In this paper, the causes of the dead zones are analyzed and simulated. Based on FSK-FM modulation, a novel RFID transceiver with enhanced readability under multipath environments is developed. The simulation results demonstrate that the proposed transceiver can remove the dead zones caused by multipath fading and enhance the readability.
