中文摘要： 毫米波无线输能是为分布式可重构卫星系统、近空间飞行器、无线传感器网络和不断小型化的无线终端供能的重要手段，已成为国际上无线输能和毫米波技术领域的研究热点。本项目重点研究Ka波段整流天线和阵列高转换效率的基本设计理论和实现方法，分别在频域和全时域内实现整流天线的协同优化；充分利用毫米波段天线和微波电路小型化的特点，将新兴的Fabry-Perot谐振器平面印刷天线和FSS（频率选择表面）覆盖层用于整流天线和阵列设计，不仅可提高接收天线增益，而且免去整流天线组成中的带通滤波器。通过优化设计理论和具体实现技术两方面来提高整流天线和阵列的"毫米波-直流"转换效率。本项目还利用毫米波高增益天线的高聚焦性能，研究基于高聚焦发射天线的整流天线协同优化方法。本项目的实施为毫米波无线输能技术在我国空间技术的应用和向产业化方向发展提供理论和实验基础。

英文摘要： Millimeter-wave wireless power transmission is the potential main power resource for lots of remote systems, such as the distributed reconfigurable satellite systems, near space airships, wireless sensor networks and the miniaturized wireless devices, and is becoming the research hotpoint in the wireless power transmission and millimeter-wave technologies areas worldwide. The fundamental design principles and techniques of Ka-band rectennas and rectenna arrays are studied in this project. The co-simulation optimization methods in frequency-domain and time-domain are proposed for analyzing and designing rectennas. Taking the advantage of the miniaturization of microwave circuits and antennas in millimeter-wave, the novel Fabry-Perot resonator printed antennas and FSS (frequency selective surface) covers are applied to design the rectennas. The receiving antennas gain will be improved and the band-pass filters could be omitted in the rectenn components by using the Fabry-Perot resonator antennas and FSS covers. The high millimeter-wave to direct current conversion efficiencies of the rectennas and arrays would be achieved by above co-simulation optimization design principle and the novel techniques of Fabry-Perot resonators and FSS. Further more, using the high focus characteristic of millimeter-wave antennas with
