Application-Adaptable Chipless RFID Tag: Design Methodology, Metrics, and Measurements
The field of chipless RFID is growing due to the cost effectiveness, simplicity, and versatility of the technology. Typically, chipless RFID tags utilize a single type of resonator in their design and are designed for a singular application. These design practices are limiting both in terms of versatility and practicality. This work builds on previous work and proposes a new application-adaptable tag design methodology. This methodology revolves around the use of combinations of multiple types of resonators in backscatter-based frequency-coded tag designs for the purpose of enhancing versatility and utility of chipless RFID technology. From this novel design methodology, an original tag design presented previously that achieves a high bit density of 27.54 bits/cm2 is further analyzed and optimized for two applications. Furthermore, this paper presents a method for associating tag response characteristics to tag geometry and develops new tag metrics that can be used to more effectively compare the merits of sensing-based tags. Measurements of manufactured tags are also presented, and associated measurement challenges are discussed.
