本論文主要研究不等線寬之磁共振接收端天線，並對天線做設計與分析，內文提及兩款不等線寬迴圈天線，皆應用於符合AirFuel Resonant規範(AirFuel聯盟)的6.78 MHz磁共振無線充電系統。先量測未加載並聯電容之實虛部阻抗，進而計算其天線Q值，再加載並聯電容驗證天線共振於6.78 MHz、磁場強度分布及傳輸係數。
探討「等線寬式」與「不等線寬式」之間的差異，並以傳輸能力較強之設計(不等線寬式)作為本論文之比較與延伸探討，再與「不等線距」做結合進行優化，使其提高傳能之效率。本文之天線設計均以平面印刷式，可以使結構比立體繞圈式更為堅固、製作難度較為簡單和可以減少所佔領體積等優點，並將天線皆設計為並聯線圈，可以降低實部阻抗，進而提升Q值。

　　In this thesis, the design and analysis of magnetic resonance receiving antennas with unequal track width are proposed. Two unequal track width loop antennas are proposed for the magnetic resonance antenna with operating frequency of 6.78 MHz. Measuring the impedance of the parallel capacitor is not added, and then calculating the antenna Q value. Finally, the parallel capacitor is loaded to verify the antenna magnetic field strength distribution and transmission coefficient.
　　Compare the difference between "Equal Track Width" and "Unequal Track Width", and use the design with strong transmission capacity (Unequal Track Width) as the comparison and extension of this thesis. Then combine and optimize with "Unequal Track Distance Width" to improve the efficiency of energy transmission. The antenna design of this paper is flat printing type, which can make the structure more solid than the three-dimensional winding type, simple structure and the area can be reduced. The antennas are all designed as parallel coils, which can reduce the real impedance and improve Q value.
