| Abstract(in English) | The objective of this study is to simplify the radiation pattern control for near-field wireless power transfer (WPT). When we use the high-frequency bands, it is expected to improve the antenna gain with large number of elements, but the control of the elements becomes more complicated. In order to reduce the number of feeding circuits and phase shifters, a partially driven method is applied to the near-field WPT, and simulation was performed. We proposed to add coupling lines and slits to improve the performance of the partially driven array. The best configuration achieved nearly 80% of the performance compared with the fully driven array. Finally, it was shown that the performance of the partially driven array maintained more than 50% of the fully driven array even when the beam was tilted to 17.9 degree. |
