Popis:	The ambient backscatter technique has attracted a lot of attention in passive communication systems. This device achieves wireless communication through radio frequency signals in backscattering Environment. In this paper, we focused on how to improve energy collection efficiency, communication rate and communication distance of passive wireless communication system. An ultralow power multi-antenna decoding algorithm and 5-stage charge pump booster rectifier circuit were proposed. The environment electromagnetic wave energy collection module, passive transmitter and passive receiver were designed. The experimental results show that communication rate of the passive wireless communication system can reach 50kbps and communication distance can reach 6 feet.
