论文摘要
远场无线功率传输（WPT）已成为物联网（IoT）和无线传感器网络（WSN）的潜在电源。功率传输范围的扩展是使技术可行的关键挑战之一。在本文中，我们通过实验研究了通道自适应的关节光束和波形结构，以扩大功率传递范围。在现实的室内环境中，在各种距离的各种无线通道中进行了WPT实验。测量数据已使用简单的分析模型拟合，以根据信号设计方案以及音调和天线的数量来分析输出直流功率和可实现的范围改进。该模型显示了信号设计与输出DC功率与可实现的范围之间的明确关系，并突出了所提出的体系结构扩展功率传输范围的重大优势。
Far-field Wireless Power Transfer (WPT) has emerged as a potential power source for the Internet of Things (IoT) and Wireless Sensor Network (WSN).The expansion of the power transfer range is one of the key challenges to make the technology viable. In this paper, we experimentally study a channel-adaptive joint beamforming and waveform architecture to expand the power transfer range. WPT experiments have been conducted in a variety of wireless channels at various distances in a realistic indoor environment. The measurement data have been fitted using a simple analytical model to analyze the output DC power and achievable range improvement depending on the signal design schemes and the number of tones and antennas. The model shows a clear relationship between signal design versus output DC power and achievable range, and highlight the significant benefit of the proposed architecture to expand the power transfer range.
