Abstract
Radio-Frequency identification (RFID) dead zones are the regions within the maximum operating range of the RFID System where the RFID reader fails to read the RFID tag. The two reasons for the emergence of dead zones - the multipath loss of signal power and impedance mismatch between tag antenna and chip are studied clearly with mathematical methods. Finally, some advices are proposed to improve the RFID performance in applications.
