本論文分為兩部分,一開始先根據傳輸線理論敘述各種傳輸線,例如:微帶線,帶線,共面波導,推導不同種類的傳輸線特性,接著利用傳輸線的特性去求得板材電氣特性公式。也將會利用相似矩陣具有相同的特徵值及使用環形共振器方法去萃取參數並驗證準確性,此外會考慮額外效應,如表面粗造度,接下來,將進行多種類型傳輸線及多層板材電氣參數萃取。
第二部分為天線設計,包含一個應用於5G通訊基地台的天線及24GHz汽車防撞雷達的天線。5G的天線使用先豐板材,在板材特性確定後,進行天線元件設計,而天線架構採用串接饋入微帶天線,以增加天線增益。先以等振幅饋入形式設計串接饋入天線,操作在Ka band,中心頻為38GHz。接下來製作在24GHz的防撞汽車雷達的天線。使用Rogers RO4003C板材,為了抑制旁波辦的大小,饋入形式以梯形能量分布。

This thesis is divided into two parts. First of all, based on transmission-line theory,different kinds of transmission line are used, for example : a microstrip line, strip line, coplanar waveguide transmission line to derive different types of properties, and then take advantage of the characteristics of the transmission line to obtain the electrical characteristic parameters of substrate. We will use similarity matrix which has the same eigenvalues and use the ring resonator method to extract and verify the accuracy of the parameters. Also additional effects, such as surface roughness and a variety of transmission lines and electrical characteristic parameters of multilayer substrate will be extracted.
The second part is about antenna design, including antennas used in 5G communications base station antennas and 24GHz automotive collision avoidance radar.The antenna for 5G uses the substrate from Boardtek and we use a series-fed antenna to increase antenna gain. Equal amplitude excitation is used at Ka band, at the center frequency of 38GHz. Next, the antenna at 24GHz for automotive radar is designed using Rogers RO4003C substrate. In order to suppress the amplitude of sidelobe, a taper distribution of excitation is used.
