Abstract

This paper presents a system that breaks the trade-off between range and power present in conventional wireless backscatter systems caused by phase noise leakage at low intermediate frequencies (IFs). By employing a self-interference cancellation chip together with a full-duplex antenna that achieves up to 125 dB of cancellation, spectral leakage can be effectively eliminated, allowing for the developed backscatter tags to operate down to 92 nW for communication at up to 32 m at 1 kb/s.
