这封信介绍了一种用于移动应用的带有平面接收器的无线功率传输 (WPT) 系统。所提出的 WPT 系统包括源线圈、发射器螺旋（Tx 线圈）、矩形接收器线圈（Rx 线圈）和矩形负载线圈。为了制作紧凑的接收器，Rx 线圈放置在负载线圈前面，间隙为 2 mm。此外，还建立了WPT系统传输效率与Rx线圈电容值之间的关系。实验结果表明，通过优化Rx线圈中嵌入的电容器，能够实现非常高的传输效率。通过 Rx 线圈上优化的电容器 Cx= 785 pF，所提出的系统的传输效率与使用超材料 (MTM) 阵列的 WPT 系统相当。拟议的 WPT 系统运行频率为 6.78 MHz。 © 2016 Wiley periodicals, Inc. 微波光学技术快报 58:1817–1819, 2016
This letter presents a wireless power transfer (WPT) system with a planar receiver for mobile applications. The proposed WPT system includes a source coil, a transmitter spiral (Tx coil), a rectangular receiver coil (Rx coil), and a rectangular load coil. In order to make a compact receiver, the Rx coil is placed in front of the load coil with a gap of 2 mm. In addition, the relation between the transfer efficiency of WPT system and the capacitance value of Rx coil is established. Experimental results show that by optimizing the capacitor embedded in Rx coil, it is capable of achieving a very high transfer efficiency. With an optimized capacitorCx= 785 pF on the Rx coil, the transfer efficiency of the proposed system is comparable to a WPT system using a metamaterial (MTM) array. The proposed WPT system operates at 6.78 MHz. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:1817–1819, 2016
