Fully Printed Chipless RFID Tags towards Item-Level Tracking Applications

Chipless Rfid Tags

a compact multi resonator circuit for Chipless rfid tag is presented in this paper. The basic resonator is a shorted λ/4 Stepped Impedance Resonator (SIR). The tag is designed and simulated using High Frequency Structure Simulator and a 6 bit prototype is fabricated on rtduroid(εr=2.2 and tanδ=.0008) Substrate in area of 4.5x2cm2. Data is coded as amplitude variations in the frequency domain. H...

Fully Printable Chipless RFID Tag

1.1 Radio frequency identification Radio frequency identification (RFID) is a wireless data capturing technique which utilizes radio frequency (RF) waves for automatic identification of objects. RFID relies on RF waves for data transmission between the data carrying device, called the RFID tag, and the interrogator (Finkenzeller, 2003; Kraiser & Steinhagen, 1995) A typical RFID system is shown ...

THZ IDENTIFICATION USING A NEW GENERATION OF CHIPLESS RFID TAGS RF and THz Identification Using a New Generation of Chipless RFID Tags

This article presents two chipless RFID approaches where data are reading using electromagnetic waves and where the medium encoding the data is completely passive. The former approach rests on the use of RF waves. The tags are comparable with very specific, planar, conductive, radar targets where the relation between the tag geometry and its electromagnetic signature is perfectly known and is u...

Time-domain Measurement of Time-coded Uwb Chipless Rfid Tags

Chipless ultra-wideband (UWB) has been proposed as a low-cost alternative for radiofrequency identification (RFID). In this paper, a comprehensible theoretical introduction to time-domain operation of a UWB RFID tag is described, and a circuit model is proposed. For commercial applications low-cost RFID readers are demanded. To this end, this paper addresses the measurement of time-coded UWB ch...
