This article describes two implementations of an Analog Devices’ signal chain-based UHF RFID reader RF front end. One implementation is based on the ADF9010 and AD9963, while the other is based on the AD9361.Abstract—In this paper, we present a simple low-cost SDR RFID UHF reader capable of reading a tag in real time. This reader is designed around a simple asynchronous OOK mod-ulator in transmission and an envelope detector in reception.
A UHF RFID reader RF front end using an AD9361 block diagram. The AD9361 transmitter monitor path gain distribution is comprised of two gains: front-end gain (transmitter monitor gain) and receive low-pass filter gain (GBBF). This paper presents a novel decoder and a BLF generator for Gen2 UHF RFID transponder. The proposed circuit removes the need for high frequency clock and generates a continuous BLF content to the Gen2 protocol.In this paper, a novel backscatter link frequency (BLF) generation scheme is presented. The accuracy of BLF required by EPC Class-1 Generation- 2 (Gen2) is one of the critical issues in UHF RFID tag design. RFID readers have to estimate the rate of the tag reply, i.e. the so-called backscatter link frequency (BLF). According to the focused EPCglobal Class-1 Gen-2 standard, the BLF can have a variation of up to +/- 22%. Most literature uses time domain algorithms to estimate this BLF.
We build portable low-cost USRP-based RFID fingerprinter and we show, over a set 210 EPC C1G2 tags, that this fingerprinter enables reliable identification of dividual tags from varying distances and across different tag placements (wallet, shopping bag, etc.). This paper introduces a backscatter link frequency (BLF) algorithm featuring high stability for passive UHF RFID tags, which is fully compatible with Information technology -Radio frequency identification- Air interface protocol at 800/900 MHz . This paper introduces a backscatter link frequency (BLF) algorithm featuring high stability for passive UHF RFID tags, which is fully compatible with Information technology -Radio frequency.All tasks specific to the RFID protocol including clock recovery, data recovery and frame detection are handled in software by a Arduino Uno micro-controller. This reader is able to generate any RFID command supported by the protocol and to decode any message backscattered by the tag in real time.
