Abstract:
A novel compact chipless RFID tag using spurline
resonators is discussed in this paper. The detection of
the tag's ID is using the spectral signature of a spurline
resonator circuit. The tag has a data capacity of 8-bits in
the range 2.38 to 4.04 GHz. The tag consists of a spurline
multiresonating circuit and two cross polarized antennas.
The prototype of the tag is fabricated on a substrate CMET/
LK4.3 of dielectric constant 4.3 and loss tangent
0.0018. The measured results show that group delay response
can also be used to decode the tag’s identity
