| dc.description.abstract | 本論文中提出以2.4GHz monopole天線為手機接收端，Dock共振器為發射端，由結合U形金屬板和patch天線所結合而成，形成耦合效率達71%以上的無線充電架構(WPT System)，並對整體建立符合振幅及相位的等效電路模型，其工作原理主要利用天線在近場內的電場耦合來達到無線充電的作用，但由於高頻天線整體接收面積過小，為使整體效率更加提升，論文中提出以U形金屬板環繞在發射端及接收端周圍的架構，並藉由等效電路模型及全波模擬方式來探討U形金屬板對之間耦合效率的影響。論文中更進一步討論到比較不同種類的天線，在同樣的情況下之間的耦合效率，最後會將WPT System的接收端做水平位移，探討不同擺放位置的效率耦合情形。 | zh_TW |
| dc.description.abstract | This thesis proposes the novel wireless power transmitting (WPT) system, and that is constructed from a transmitting dock resonator and a 2.4GHz receiving monopole antenna to demonstrate the efficient characteristics. The microstrip patch and the U-shape metal plate are employed in the dock resonator design. The presented WPT system exhibits high-power transfer efficiency up to 71% and the equivalent circuit is established to obtain the amplitude and phase performances. To improve the coupling of wireless charging by the near-field electrical coupling, the transmitting antenna and the receiving antenna are encircled with the U-shaped metal plate. According to the equivalent-circuit and the full-wave simulations, the effects of U-shaped metal plate can be analyzed. Compared to the WPT system using different structures, the proposed architecture provides the largest efficiency. Finally, horizontally shifted the receive antenna of WPT system exhibits high-power transfer efficiency distribution. | en |
