在这封信中，我们提出了一种使用可重构发射/接收天线的近场无线功率传输(WPT)系统。该可重构天线由带开关的寄生元件组成。通过切换开路/短路端来改变WPT系统的阻抗，当发射/接收天线出现不对准时，可以改善阻抗匹配条件。从而降低了阻抗失配损耗，大大提高了电能传输效率。数值仿真结果表明了该系统的性能。
In this letter, we propose a near field wireless power transfer (WPT) system using reconfigurable transmitting/receiving antenna. The reconfigurable antenna is composed of parasitic elements with switches. Impedance of WPT system is changed by switching open/short termination and impedance matching condition can be improved when the misalignment of transmitting/receiving antenna are occurred. Therefore, the impedance mismatching loss is reduced, the power transmission efficiency is greatly increased. Result of numerical simulation shows the performance of the proposed system.
