Abstract

Information cannot be transferred wirelessly independent from power. Therefore, an aperture-to-aperture transfer with high efficiency is critical for no matter information and power transfer systems. Nevertheless, the aperture-to-aperture transfer efficiency always suffers TX/RX antenna polarization misalignments. In this work, an aperture-to-aperture transfer scheme is proposed to enable maximum power link from linearly polarized electromagnetic wave without any worry on polarization tilt (i.e., polarization-independent). The aperture-to-aperture scheme is modeled by S-parameters of three-port network, and validated with rigorously theory analysis and experiment measurements, which is perfect for the simultaneous wireless information and power transfer.
无线信息与功率同步传输的偏振无关孔径传输方案
信息不能独立于电源进行无线传输。因此,高效的孔径传输对于任何信息和功率传输系统都是至关重要的。然而,孔径间传输效率总是受到TX/RX天线极化失调的影响。在这项工作中,提出了一种孔径到孔径的传输方案,以实现线性极化电磁波的最大功率连接,而无需担心极化倾斜(即偏振无关)。采用三端口网络的s参数对该方案进行了建模,并进行了严格的理论分析和实验测试,证明该方案能够同时实现无线信息和电力传输。
