本研究主要工作是設計雙頻帶微帶天線應用於特定短程通訊(Dedicated Short Range Communications, DSRC)中。另外為了配合天線設計最佳化，我們提出一個最佳化程式。此程式能與商用軟體IE3D結合使用，並且在程式運算時，能利用基因演算法，達到天線參數最佳化之目的。在設計DSRC天線的過程中，我們利用此程式來使得天線阻抗與頻寬產生最優之表現。我們可觀察出此最佳化之天線與初始設計，有著明顯的變化。並且由量測與實作的驗證，來確定其模擬最佳化之有效性。希望本研究能提供未來的天線設計者，創造出一個新的設計方法與設計概念。

A dual band patch antenna design that covers two unlicensed bands of DSRC(Dedicated Short Range Communications, DSRC) applications is proposed in this work. In order to optimize the initial design performance, the genetic algorithm is implemented in conjunction with the IE3D simulation software to adjust the geometric parameters of the patch. The automated control program examines the fitness of the design via input impedance and bandwidth of an antenna design and utilizes the natural selection method to generate new designs. The migration of antenna characteristics in the simulated and measurement results agrees and shows apparent performance improvement.
