K-State Resonators for High-Coding-Capacity Chipless RFID Applications

Directly Printable Frequency Signatured Chipless RFID Tag for IoT Applications

This paper proposes a low-cost, compact, flexible passive chipless RFID tag that has been designed and analyzed. The tag is a bowtie-shaped resonator based structure with 36 slots; where each patch is loaded with 18 slots. The tag is set in a way that each slot in a patch corresponds to a metal gap in the other patch. Hence there is no mutual interference, and high data capacity of 36 bits is a...

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 Printed Chipless RFID Tags towards Item-Level Tracking Applications

Chipless RFID, an emerging technology

Radiofrequency identification (RFID) is an established technique for automatic data captures exploiting reflected electromagnetic waves by scatters, usually called tags or transponders. In the last decades, roughly since the mid-1960s, very effective integrated circuit-based tags have been developed and implemented in numerous applications from the most simple like the electronic surveillance a...

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 ...
