- *Abstract
-
An RFID tag system has been developed that can perform accurate localization for indoor applications. The technology integrates with non-linear transmission lines (NLTL) for harmonic generation to solve the multi-path interference problems of using other systems indoors. The NLTL are designed with broadband or multi-band properties, offering ready matching to antenna front-ends, and solving phase ambiguity by adopting multiple frequencies. Capable of localizing objects to the millimeter range, this invention has potential uses in a broad range of applications from inventory management to security monitoring.
Potential Applications:
- Real-time object localization
- Security monitoring
- Inventory management
- Multiplexing non-directional remote reading
- Gaming systems
Advantages:
- Compatible with standard CMOS processing or printed circuit board
- Easy antenna matching due to broadband or multi-band RFID properties
- Simplified reader design due to continuous wave adoption
- High positioning accuracy
