由於同軸共線天線(Coaxial Collinear Antenna)製造簡單容易,相對的製造成本較低,因此,漸被廣泛作為基地台天線使用。
本文將簡介其原理,並自行設計及製作,再利用學校無線通訊實驗室之微波暗室,及近場量測系統,量測該天線之場型特性,以進一步了解於不同平面不同距離處,同軸共線天線之電流振幅及相位分佈。

Due to the characteristics of simple configuration , easy and low-cost manufacturing process , the Coaxial Collinear Antenna is now getting more attention in antenna community and also widely adopted for base station of cellar communications.
This thesis first introduced its principle briefly followed by designing and manufacturing an modified Coaxial Collinear Antenna in practice. Then we used the microwave chamber of the Wireless Communication Laboratory and near field measurement system to measure the pattern characteristic of the antenna for further analysis . The analysis of the current amplitude and phase distribution of Coaxial Collinear Antenna at the different plane and distance will then help improve the design parameters for better performance.
