Abstract

Abstract: Simultaneous wireless information and power transfer (SWIPT) is intended to transmit information and energy simultaneously over the wireless channels. As a major component of SWIPT, a rectifying circuit is an essential influencing factor for power conversion efficiency of SWIPT. Closed-form equations of power conversion efficiency and input power of rectifying circuit were derived to predict the performance. This simplified model is useful for circuit design and optimization. The result of theoretical analysis and ADS simulation shows that Ultra Narrow Band (UNB) signal has a sine-like performance in wireless power transfer. Using UNB signal as a novel modulation scheme, and provides a new feasible way for SWIPT.

Key words: simultaneous wireless information and power transfer, microwave power transfer, rectenna, schottky-barrier diode, ultra narrow band
