Abstract:
A novel compact RFID tag employing open stubs in a
microstrip transmission line is proposed. The prototype of the tag is
fabricated on a substrate of dielectric constant 4.4 and loss tangent 0.0018.
The tag consists of microstrip open stub resonators and cross polarized
transmitting and receiving disc monopole antennas. A prototype of 8 bit
data encoded tag is demonstrated in this communication. Method for
enhancing the performance of the RFID tag is also proposed. Magnitude
or group delay response can be used to decode the tag informations

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
