Radio Frequency Identification is a rapidly growing technology. Recent
advances in wireless technology pave a path for integrating sensors with
RFID system. The proposed tag consists of multiple resonators which are
used for encoding the data. The tag can also be used for sensing
applications by integrating dedicated resonator with the sensor element.
Each spiral resonator is of a different length to encode data at
different frequencies. Also, the length of spiral resonator and
separation between them is adjusted so that there will be no coupling
between them. The data encoding capacity is increased by increasing
number of spiral resonators (of different length). The 12-bit encoded
data is obtained among which 11-bits are used to encode the chipless
RFID tag ID for tracking/identification, and the remaining one bit is
used for sensing. The dimensions used in this design are 16.30 cm x 6.63
cm and analysis is carried out for both Taconic TLX (TM) and Rogers
4003C (TM) substrates. For 12-bit multi-resonator design using Rogers
4003C (TM) substrate, the overall bandwidth utilization is 1.7 GHz (1.2
GHz-2.9GHz). The tag can be used in various low-cost sensing
applications. The encoding capacity can be further increased by adding
more spectral resonators.
