Abstract :
We present a harmonic radio frequency identification (RFID) transponder based on reflective nonlinear transmission lines (NLTLs), where the tag size is significantly reduced with single antenna configuration. To show the feasibility and design procedure, two open-ended NLTLs are fabricated in IBM 0.13μm CMOS process. Both of the 0.35 mm by 0.95 mm open-ended NLTLs show around -11 dBm reflected second harmonic by 0 dBm small signal input. Distance of wireless transmission is characterized by single dualband/broadband antenna connection.
