Abstract

We demonstrate for the first time that a multicarrier signal, and in particular an OFDM signal, can be generated by backscattering a single carrier incoming electromagnetic wave. This is achieved by utilizing a semi-passive IQ backscatter modulator involving two transistors with varying biasing in a Wilkinson power divider architecture that has previously been proposed and demonstrated for Quadrature Amplitude Modulation (QAM) and Chirp Spread Spectrum (CSS) modulation schemes. The multicarrier backscattering signal is synthesized in time domain. This capability enables low-cost and low-power consumption tags to significantly improve the transmission data rate and potentially communicate with the commercial wireless networks such as WiFi and LTE.
