Test and measurement procedures for RFID systems

The necessity of having instruments for analyzing the quality of signal received by the reader from the transponder is more and more important in order to evaluate the performance parameters of RFID systems. In this paper we review the existing test procedures and transponder simulators that proved their utility in the development of SLRM1000 RFID system. We propose a new measurement device and procedure that produce 2D maps of the quality of the received signal as the position of the transponder is varied across the antenna.
