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 (G BBF).
An overview of Ultra High Frequency (UHF) Radio-Frequency Identification (RFID) practical applications and the reader antenna design requirements are presented in this paper.This document provides a general overview on basics of UHF wave propagation, as well as practical considerations of UHF label antenna design. The target is to guide the reader to a good understanding of UHF label antenna design in theory and in practice.Abstract— We describe a UHF RFID reader which uses low cost off-the-shelf components such as MSP430 microcontroller and the TH7203x transmitter IC. The receiver circuit is based on envelope detector and analog data slicer. The design is very simple and can be used as an educational tool for academic research.
In the UHF RFID system, the reader sends information to one or more tags by modulating an RF carrier using amplitude shift keying (ASK) with a pulse-interval encoding (PIE) format. Tags receive their operating energy from the reader’s unmodulated RF carrier.In this paper, two different designs of an ultra-high-frequency (UHF) RFID reader antenna are presented in detail. The first one is a narrowband antenna, suitable for the frequency band of the ETSI standard (865–868 MHz), and the other one is a wideband antenna that operates in both the frequency bands of ETSI and FCC (865–928 MHz) standards.
Simple Low Cost Open Source UHF RFID Reader. 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 .Due to the huge complexity of the design, this chapter explains how to design a UHF RFID Reader from the theoretical point of view and describes the necessary components to carry out the design. Reader is a key component of a RFID application system. Based on the ARM9 chip S3C2440, the UHF reader ASIC AS3990 and a battery charger 9-channel programmable DC-DC power management chip SMB122, a low-power handheld UHF RFID reader is designed and implemented in this paper.Abstract — In this article, a new antenna design for Radio-Frequency Identification (RFID) reader applications in the Ultra High Frequency (UHF) band has been proposed. The antenna is a perfect electrical conductor, excited by a 50 ohms microstrip line, set on an Epoxy FR-4 substrate. His overall size is (98*98*1.6) mm3.
