Abstract :
A new method of reading chipless RFID tags in the near-field region using a microstrip transmission line and resonant coupling with the tags is proposed. A chipless tag consist of combinations of two resonant structures using different resonance methods and resonance frequencies. N-bit codes distinguish 2n types of items by passing over the microstrip transmission line as the reader system. This method can be used effectively in paper/plastic-based items, especially required to improve security as the additional security element. It will be the effective way to identify chipless RFID tags in the near-field region.
