To overcome the main limitation of current UHF-based RFID standards, recently RFID solutions employing ultra-wideband (UWB) signals and working at millimeter-wave or THz bands have been proposed, both as stand-alone systems or as add-on in UHF tags (hybrid RFID).
Such technologies are expected to bring several advantages in new applications requiring, for instance, high-localization accuracy, reader/tag miniaturization, and efficient energy transfer.
However, several issues have to be tackled before their adoption such as backscatter channel modeling and antenna design for millimeter-wave/THz bands, chip design, identification and localization algorithms design, use of new materials, etc.
List of topics:
- Hybrid UHF-UWB RFID
- Chip design for UWB/mm-wave RFID
- UWB/mm-wave/THz backscatter channel characterization and modeling
- Mm-wave identification and sensing
- THz identification and sensing
- Antenna design
- MIMO RFID
- High-accuracy localization
- Test bed
