Compact Printable Chipless RFID Systems
IEEE Transactions on Microwave Theory and Techniques, 2015Two novel compact printable chipless RFID systems are presented, which are: 1) a dual-polarized (DP) system and 2) an orientation insensitive (OI) system. Chipless tags for both the DP and OI systems consist of horizontally (H) and vertically (V) polarized “I” shaped slot resonators of different lengths, which create frequency signatures in the ...

UWB Reflectarray Antenna for chipless RFID applications
2014 31st National Radio Science Conference (NRSC), 2014The main limitation of any chipless Radio Frequency Identification (RFID) system is the very short reading range. In this paper, we propose an Ultra Wideband (UWB) Reflectarray Antenna (RA) system with 2.2 GHz bandwidth centered at 6 GHz for the reader of chipless RFID applications.

Chipless RFIDs by using metasurfaces
The 8th European Conference on Antennas and Propagation (EuCAP 2014), 2014High-Impedance Surfaces comprising multi-resonant elements are proposed as chipless tags. The presence of the ground plane in the structure is a key point in realizing a chipless RFID nearly insensitive with respect to the objects which the tags are placed on.

Spatial-Based Chipless RFID System
IEEE Journal of Radio Frequency Identification, 2019Conventional techniques in chipless radio frequency identification (RFID) systems are incapable of fully overcoming the key challenges of modern identification applications, including high data capacity, low tag cost, and reliable operation. The idea of electromagnetic imaging in chipless RFID systems is a promising technique that shows many advantages

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 for space applications
2014 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE), 2014Recent works reveal a great deal of interest in the subject of wireless passive sensor for space applications. In particular, wireless passive tags can be employed during in-flight operations as well as during ground test campaigns, thanks to their robustness in extreme environments since they do not contain batteries nor any active electronic circuits.

MIMO based chipless RFID system
2012 IEEE International Conference on RFID-Technologies and Applications (RFID-TA), 2012Chipless RFID systems are perhaps the most eligible candidate for catering the demand of low-cost multiple item tagging in future. However, the absence of a microchip in chipless tags limits the processing capabilities hence the RFID reader has to improvise most of the processing.

A chipless RFID readable on metallic objects
2013 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2013High-Impedance Surfaces (HIS) are proposed to be employed as a trasponder for Radio Frequency IDentifcation (RFID). The HIS comprises a multi-resonant Frequency Selective Surface (FSS) on top of a grounded thin dielectric slab. The presence of the ground plane is particularly useful to mounting the transponder on top of metallic objects and in general ...

Low Cost Chipless RFID Systems
2012This chapter presents a comprehensive overview and novel classification of chipless RFID tags that can be found in the market and reported in peer-reviewed conferences and journals. The problems of achieving low cost chipped RFID are presented along with the proposed solution of chipless RFID for lowering the price of the RFID tag.
