本論文提出無線充電之磁共振系統與天線設計，並對天線做設計與分析，應 用皆於符合AirFuel Resonant規範(AirFuel聯盟)的6.78 MHz磁共振標準。利用電磁模 擬軟體(HFSS 18)進行分析以及優化，天線加載並聯電容達共振於6.78 MHz，並探 討磁場分佈、S參數及兩天線之間傳輸係數。
內文提出兩款磁共振天線，分別為發射端(Tx)與接收端(Rx)磁共振天線，天線 均採用帄面印刷式設計，相較於傳統立體繞圈式更為堅固使線圈不易受到擠壓變 形且製作較容易，解決了體積過於龐大之缺點，內文中接收端天線使用雙路徑繞 線的方式繞製，線圈的末端透過跳線連接至線圈的饋入端，可以達到整體線圈的 降阻，並將天線皆設計為並聯線圈提升Q值。
在最後將兩種天線結合系統，並與市面上的無線充電版做比較，進行無線電 力傳輸測詴，透過不同距離接收到的電壓值以驗證共振線圈傳輸之可行性，比較 線圈之間的差異，期望將來能與實際產品做整合。

In this paper, the design of the magnetic resonance system and antenna for wireless charging is proposed, and the antenna is designed and analyzed for the 6.78 MHz magnetic resonance standard in accordance with the AirFuel Resonant Specification (AirFuel Alliance). Using electromagnetic simulation software (HFSS 18) for analysis and optimization, the antenna is loaded with parallel capacitors up to 6.78 MHz and discuss magnetic field distribution, S parameters, and transmission coefficients between the two antennas.
The article proposes two magnetic resonance antennas, which are the transmitter (Tx) and receiver (Rx) magnetic resonance antennas. The antennas are designed with flat printing, compared to the traditional stereoscopic coil type more robust so that the coil is not easy to be squeezed deformation and make easier to make. To solve the shortcomings of being too bulky, the receiver antenna is wound by a dual-path winding method. The end of the coil is connected to the feed end of the coil through a jumper, which can achieve the resistance reduction of the overall coil, and the antennas are designed as parallel coils in order to increase Q value.
At the end, the two antennas are combined with the system, and compared with the wireless charging version on the market, and the wireless power transmission test is carried out. The voltage values received at different distances are used to verify the feasibility of the resonance coil transmission and compare the differences between the coils. Looking forward to integrating with actual products in the future.
