In this paper, we describe the sensitivity and impedance measurement method for UHF RF identification (RFID) chips. The measurements are performed using an RFID tester (RFID reader with variable output power and frequency) and a vector network analyzer.Abstract—This paper shows that the classical conjugate impedance matching used in the UHF RFID is not optimal anymore with new chips that have high sensitivity. The optimal matching allowing to maximize the read range of an RFID system (reader and tag) is introduced.As mentioned before, in RFID systems, both forward and reverse links are important. The tag characteristic important for a forward link is the tag sensitivity - the minimum signal strength (field or power) at the tag location needed to read the tag. The tag power sensitivity is related to the chip (IC) sensitivity Pchip as: Pchip =Ptag pGτSensitivity and Impedance Measurements on UHF RFID Transponder Chips. Abstract. We present a method to perform accurate measurements in the UHF (ultra high frequency) band on passive RFID (radio frequency identification) transponder chips. Our samples were extracted from com-mercially available RFID tag inlays.
Read sensitivity is a measure of the ability of an RFID chip or tag to detect and respond to signals from an RFID reader. On the other hand, write sensitivity is a measure of the ability of an RFID chip or tag to receive and encode data from an RFID reader during the writing process. This article describes an alternative procedure for measuring the impedance of an ultra high frequency (UHF) radio frequency identification (RFID) chip and finding its turnon-point using a standard vector network analyzer and a custom . This paper presents a detailed characterization of passive UHF-RFID tags using measured power activation profiles. Factors such as chip sensitivity, antenna dimension, and conjugate impedance matching are taken into account.Abstract—In this paper, we describe the sensitivity and impedance measurement method for UHF RF identification (RFID) chips. The measurements are performed using an RFID tester (RFID reader with variable output power and frequency) and a vector network analyzer.

Evolution of RFID chip sensitivity and read range for ETSI regulation. (Estimated theoretical read range considering: operating frequency at 868 MHz, reader power 2 W ERP, reader antenna gain 2 dBi, tag antenna is ideal dipole and . The read and write sensitivity values of a passive UHF RFID tag are expressed in dBm because they represent the minimum power level required for the tag to be read or written to by an RFID reader. In this paper, we describe the sensitivity and impedance measurement method for UHF RF identification (RFID) chips. The measurements are performed using an RFID tester (RFID reader with variable output power and frequency) and a vector network analyzer.
