Abstract
A beam-steering backscatter circuit in an integrated tag device. The circuit includes an antenna array and SP4T reflector array configured to receive and transmit through the antenna array. A baseband phase-shifting module modulates an incident signal based upon tag data to create an output signal and re-radiates the output signal with a controllable angle of direction through the SP4T reflector array. A phase locked loop synchronized with a wake-up receiver provides an intermediate frequency (IF) clock to the baseband phase shifting-module.
