Detecting RFID chipless technology with software programmed radio: a study of slit and line configurations

Abstract

The aim of this study was to investigate the potential for monitoring chipless RFID technology using a radio transmitter and receiver. The researchers analyzed the behavior of a printed label made with an aluminum-based ink from a thermal printer and compared the read characteristics of the receptor with a baseline. The results showed a shift in the reading characteristics near the resonance point of the curve. In the resonance area, the coded signal deviated from the baseline, floating above the baseline in the slit configuration and below in the line configuration. These observations provide valuable insights into the performance of chipless RFID technology and the potential to optimize its functionality. Chipless RFID technology has the potential to revolutionize the packaging industry by offering a cost-effective and efficient means of tracking and managing inventory. Unlike traditional RFID tags, chipless RFID utilizes the unique characteristics of the packaging material itself to store and transmit data, eliminating the need for expensive chips and simplifying the manufacturing and assembly process. Real-time item tracking, product quality and safety monitoring, and improved supply chain management are among the benefits of chipless RFID, with the potential to enhance efficiency, reduce waste, and increase profitability for companies.
