摘要

提出了矩形导电平面上由非平衡馈电超低轮廓倒L型天线组成的WPT系统，并对其进行了数值分析。通过调整水平单元的长度和馈线点的位置，将发射天线和接收天线的输入阻抗匹配到50欧姆。导电平面的尺寸为550 mm × 1283 mm。天线高度h为70mm(波长/43)。在发射天线与接收天线之间距离为140 mm的情况下，在设计频率为100 MHz时，功率传输效率为92.2%。

Mutual coupling characteristics of two unbalanced fed ultra low profile inverted L antennas closely faced each other

The WPT system composed of the unbalanced fed, ultra low profile inverted L antenna on a rectangular conducting plane is proposed and analyzed numerically. The input impedances of transmitting and receiving antennas are matched to 50 ohms by adjusting the length of horizontal element and the feed point position. The size of conducting plane is 550 mm by 1,283 mm. The antenna height h is 70 mm (wavelength/43). In the case of the distance between transmitting and receiving antennas is 140 mm, the power transfer efficiency becomes 92.2% at the design frequency of 100 MHz.
