摘　　要：介绍了微波输能(MPT:Microwave Power Transmission)系统的工作原理和系统组成,指出系统各部分的技术水平。其次,对MPT技术的发展和应用做了全面概述,它主要用于太阳能卫星、临近空间飞行器等远距离输能,目前在低功率应用领域得到关注。然后对微波无线输能系统的关键技术——整流天线研究进展做了详细分析。最后,讨论了微波输能技术的发展前景和尚待攻破的技术难题。Firstly, the operation principle and components of Microwave Power Transmission（MPT） system are introduced and the recent developments of every component are summarized. Secondly, applications and developments of MPT technology are reviewed. MPT technology is mainly applied in far distance power transmission, such as Solar Power Satellite（SPS）and aircrafts in the near space and is now noticed in low power applications. Thirdly, the status in quo of the key technology, rectennas, is analyzed in detail. Lastly, prospects of MPT technology and problems to be solved are discussed.
