Polarization-Independent Aperture-to-Aperture Transfer Scheme for Simultaneous Wireless Information and Power

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.
