Abstract

The design of a low-cost, flexible, miniaturized and a high code density chipless RFID tag is presented as a solution for tracking the transportation of biomass fuel pellets. The performance of the tag is presented and demonstrates the applicability of the design for different material systems, whilst maintaining a compact size of 5.06cm 2. The tag consists of nested concentric hexagonal elements and a central spiral resonator suitable for ID encoding. The tag presented demonstrates code density of 3.6-bits/cm 2 , possesses angular stability up to 60º and high radar cross-section. The tag performance was also observed for tracking 5kg of fly ash biomass. Additionally, as the tag mass mostly consist of FR4, PET or Taconic TLX-0 with a minute mass of either copper, gold or silver, the tag can be easily combusted and disposed of during biomass combustion. The novel features of this tag are the combination of hexagonal and spiral shape slots for maximum space utilization thereby achieving high RCS signatures along with high code density. All these properties of the proposed chipless RFID tag provides a pioneering pathway for a real-time biomass tracking application.
