A novel proposal of chipless RFID using layered metal patches

The application of RFID tags are spreading, finding use in our everyday life. Many potential uses are not practical with the present day RFID technology due to high cost and limited range of operation. The present work focuses on developing a sub-cent RFID capable of operating from a reasonable distance, though with some compromise on the number of bits of information that can be stored in the tag. Since there are ample applications of read-only RFID with limited information content, the present technology is expected to fill a substantial part of the niche of applications with sub-cent tags.
