作为一种新兴框架，可移动天线（MA）赋能的无线供能网络（WPNs）已引起越来越多的关注。WPNs将无线通信与能量传输相结合。MA通过引入额外的空间自由度，能够动态调整天线单元的位置，从而充分利用信道增益，优化能量波束成形的效果，并进一步提升WPNs的性能。本文首先对MA的实现方式进行分类，并回顾WPNs的基本原理。随后，我们重点阐述了MA赋能的WPNs在提升无线能量传输效率、实现灵活自适应波束成形以及增强系统鲁棒性和抗干扰能力方面的关键优势。此外，本文讨论了四个代表性应用场景和三项关键使能技术。文中还通过一个案例研究展示了MA为WPNs带来的能量收集性能提升。最后，我们探讨了MA赋能的WPNs所面临的挑战和未来发展方向，旨在为未来的研究和实践提供参考。

英文摘要

As an emerging framework, movable antenna (MA)-enabled wireless powered networks (WPNs) have attracted growing attention. WPNs integrate wireless communication and energy transfer. MA can dynamically adjust the position of antenna units by introducing additional spatial degrees of freedom, so as to make full use of channel gain, optimize the effect of energy beamforming, and further improve the performance of WPNs. In this article, we first classify the implementations of MA, and review the fundamental principles of WPNs. We then highlight the key advantages of MA-enabled WPNs in enhancing wireless power transfer efficiency, realizing flexible and adaptive beamforming, and improving system robustness and interference resilience. Furthermore, four representative application scenarios and three key enabling technologies are discussed. A case study is also presented to show the improvement of energy harvesting performance brought by MA for WPNs. Finally, we discuss the challenges and future directions of MA-enabled WPNs, aiming to provide reference for future research and practice.
