Abstract

This paper focuses on the basic concepts of chipless Radio Frequency IDentification (RFID) tag at 30 GHz destined for short range applications. Chipless RFID is proposed as the solution for low cost item tagging. The chipless tag encodes data into the spectral signature using a multiresonator. Both amplitude and phase components of the spectral signature are used for data encoding. The chipless RFID tag is a prototype and comprises of a microstrip multiresonating circuit with 6 spiral resonators and two cross-polarized transmitting and receiving circular UWB monopole antennas. Commercial based software, the finite-integration technique is used to investigate the characteristics of the chipless RFID tag.
