One key element of a chipless RFID system is the tag. Since it is chipless, it acts both as the scatterer and encoder. As the scatterer, it needs to reradiate the incident field as much as possible in order to maximize signal-to-noise ratio (SNR) in the reader. As the encoder, it needs to encode a high density of data on the backscattered signal. There

Simple Chipless RFID Tag Configurations
2018 IEEE Asia-Pacific Conference on Antennas and Propagation (APCAP), 2018Two unique configurations of chipless RFID tag are reported in this paper. They consist of integrated Lresonators and cross polarized transmitting and receiving circular patch antennas. The validations of the proposed designs have been carried out using 8-bit data encoded tags, for the frequency band of 3.3–5.8 GHz, and microstrip circular antenna ...

Chipless RFID Tags: Co- or Cross-Polar Tag?
2019 IEEE Asia-Pacific Microwave Conference (APMC), 2019This paper provides a comparison between two types of co- and cross-polar frequency-coded chipless RFID tags considering their electrical parameters. These parameters are the level of radar cross section (RCS), data capacity, rotation sensitivity, and resistant to interferences. A brief description of each parameter is given.

High-density compact chipless RFID tag for item-level tagging
2018 International Applied Computational Electromagnetics Society Symposium (ACES), 2018This paper presents 36-bit compact passive chipless RFID tag. The bowtie shape based tag structure is loaded with 36 slots. The tag is capable of yielding high data density. The overall tag dimension is 27mm × 26mm. The tag structure is optimized and analyzed for three different substrates, i.e., FR-4, Taconic TLX-0, and Rogers RT5880. Each loaded slot

Chipless RFID tag with integrated sensor
2010 IEEE Sensors, 2010A chipless tag based on multiresonators with integrated temperature sensor is presented. The tag consists of a UWB monopole antenna loaded with multiple cascaded spiral EBGs which have a 1∶1 correspondence with data bits. The data bits are encoded into the spectrum hence the tag has a unique spectral signature. The chipless tag is less sensitive to tag

Improved chipless tag based on multifilters
Microwave and Optical Technology Letters, 2017AbstractIn this study, a novel compact chipless RFID transponder is presented. The coding information is based on spectral signature using three types of multiresonator: spiral, slot, and U‐shaped defected ground structure (DGS). Each resonator can be seen as a band‐stop filter which contributes to a particular resonance frequency.

UCR: An unclonable chipless RFID tag
2016 IEEE International Symposium on Hardware Oriented Security and Trust (HOST), 2016While Radio Frequency Identification (RFID) has become popular for commodity and asset tracking and management, the relatively higher price of RFID tags limits its application in the supply chain of low-cost commodities. Recently, cost-effective chipless RFID tags that do not contain a microchip in the transponder have been gaining more attention from ...

Chipless RFID tag for light sensing
2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014A fully passive chipless RFID tag with light sensing capabilities is presented for low-cost, maintenance-free applications. This paper describes the steps towards developing a prototype of passive light sensor using off the shelf photoresistors. Results show a single microwave resonator has 60 MHz frequency shift and 7.5 dB power variation for 0 to ...
