Design and Analysis of an Octagonal Chipless RFID System

The proposed research introduces an approach to design an Octagonal chipless RFID tag to achieve tag identification to encode the information. These tags work by reflecting a unique electromagnetic signal when it is read by an RFID reader. The unique characteristics of the tag's structure or material cause modulation or reflection of the radio waves, which can be decoded by the reader to retrieve stored information. In this research, we propose an innovative approach for designing chipless RFID tags using electromagnetic resonators arranged in a 2x2 matrix configuration. While the design can be adapted to any nxn matrix, we specifically focus on the 2x2 arrangement in this study. The resonators are strategically positioned to achieve optimal performance, considering read range, robustness, and scalability factors. This paper provides a comprehensive review of Chipless RFID technology, covering its working principles, encoding techniques, applications, advantages, and challenges.
