Performance evaluation of passive Radio Frequency IDentification (RFID) Tags is a very challenging task and commercially available solutions for Tag testing are very expensive and not totally flexible. In this work, we propose a novel approach for the characterization of RFID Tags with Software-Defined Radio (SDR). We show how a cheap (below 1000$) and flexible SDR-based RFID Reader can be turned into an accurate tool for measuring the goodness of the conjugate matching between the RFID chip and the antenna which primarily affects the Tag sensitivity. We test our platform by analyzing the performance of two built-in-lab Tags: measurements show a strong agreement with theoretical and simulation results.

Abstract
Performance evaluation of passive Radio Frequency IDentification (RFID) Tags is a very challenging task and commercially available solutions for Tag testing are very expensive and not totally flexible. In this work, we propose a novel approach for the characterization of RFID Tags with Software-Defined Radio (SDR). We show how a cheap (below 1000$) and flexible SDR-based RFID Reader can be turned into an accurate tool for measuring the goodness of the conjugate matching between the RFID chip and the antenna which primarily affects the Tag sensitivity. We test our platform by analyzing the performance of two built-in-lab Tags: measurements show a strong agreement with theoretical and simulation results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
