WS2: Chipless RFID Future and Challenges

Organisers

Mohamed El-Hadidy and Thomas Kaiser, Duisburg-Essen University, Germany

Abstract

RF-Barcode of the future:This workshop aims to construct a solid platform for interactive discussions between the researchers from RF, signal processing, communication and networking societies for sharing their objectives, challenges, experiences and future solutions for chipless RFID systems.

The requirements of the multi-tag scenario for chipless RFID systems illustrated in Fig. 1would be proposed. Furthermore, the printability, nonlinearity and sufficient coding capacity of the tag will be introduced as optimum solutions to dethrone the barcode from item level labelling. Increasing the reading range using enhanced UWB, high gain, pencil beam and steering reader antenna will be illustrated.

This workshop will introduce a novel collision avoidance protocol for the chipless RFID systems. The protocol will be presented as the first Medium Access Control (MAC) algorithm for handling the multi-tag identification scenario of the frequency signature based chipless RFID tags.

Novel techniques for chipless RFID multi-tag detection and identification, enhancing the system latency and increasing encoding capacity would be introduced. The channel and environmental effects on the chipless RFID tag detection will be deeply discussed. Smart channel estimation and equalization algorithms in dense multipath propagation scenarios will be presented.
