DEVELOPMENT OF RF/RFID SYSTEMS FOR CONTROL AND REGISTRATION OF GOODS AND PERSONNEL

Abstract: 

This project spearheads the design, optimization and implementation for an RFID system prototype in the UHF frequency range, in accordance with European standards. Furthermore, the project intends to create a research infrastructure and critical know-how that will enable several new applications of backscatter radio, e.g. backscatter sensor networks. Even though the principle of backscatter communication, i.e. communication by means of signal reflection/scattering rather than radiation, dates back to World War II, commercial systems have started to proliferate quite recently.

The project will crystallize a solid methodology for tag design and backscatter efficiency optimization, exploiting the tag antenna structural mode, largely missed in existing tag designs. Current art in the field is not optimal, perhaps due to the fact that antenna scattering properties are significantly different than antenna radiation. A software-defined radio (SDR) approach will be followed to design and prototype a tag reader. Such an approach will accelerate research on linear, non-linear, coherent and non-coherent detection techniques, tailored to the round-trip, backscatter radio channel, which is significantly different than the conventional radio channel. The SDR approach will also facilitate experimentation with new backscatter radio protocols and applications. Reader network of antennas are needed so that coverage is maximized, while inter-reader interference and implementation cost are kept minimal.

Low-complexity, beam-switching antennas with Butler matrix beam-forming networks (BFN) will be explored, as low-cost candidates for the reader antennas. Computation-efficient ray-tracing, as well as analytic, iterative methods will be further explored, to provide a software package that automates planning (e.g. Reader locations) and optimizes coverage. Finally, the whole system prototype will be experimentally evaluated and thoroughly contrasted with existing state-of-the-art systems.
