New generation of RFID technology - Smart identification, no chip required

Ref.-No. 7142

Keywords: RFID technology, chipless RFID, Multi-Tag Detection, Clutter Mittigation, frequency-coded RFID tags

In the world of Industry 4.0, logistics, and automated processes, identifying objects is a decisive factor in determining success. But conventional RFID technologies quickly reach their limits – especially in complex, high-interference environments and whenever many tags must be detected simultaneously. A new, innovative technology from the University of Duisburg-Essen’s Institute of Digital Signal Processing now offers a forward-looking solution. It combines harmonic and frequency-coded (FC) chipless RFID technology. 

The new method of identifying and reading out electronic tags involves an electronic tag, a transmitter, a receiver, and an analysis unit. The tag contains a transceiver that receives narrowband high-frequency signals and transmits them at double the frequency and a resonator that does not reflect high-frequency radiation at the resonance frequency. It completely eliminates electronic chips and tag power supply, making tags cheap, robust, and flexible in use. 

Competitive Advantages

  • low cost
  • autonomous tag power supply
  • simultaneous detection of multiple tags (multitagging)
  • can be used in high-interference environments

Commercial Opportunities

The innovative technology not only makes tag identification more reliable, but allows tags to contain much more information. The system’s ability to reliably detect multiple tags simultaneously even in high-interference environments without superposition or information loss is of particular importance. Elimination of chips makes the tags not only cheaper and more robust, but also more sustainable. Companies benefit from more efficient processes, lower maintenance costs, and a technology that is easy to integrate into existing processes. Example areas of application include logistics, goods monitoring, and livestock farming.

Current Status

An application has been filed with the DPMA. It can be expanded to other countries in the priority year. On behalf of the inventing institutions, we are offering the technology for refinement and for commercial licenses.
