| 摘 要： | 主要分析了一种带有反射面圆形阵列天线。首先根据方向性增强原理，对一般性的不带反射面的圆形阵列天线进行了理论上的分析，计算得到了阵列天线各个阵元的配相，然后根据镜像原理，得到了在中心带有反射面时圆形阵列天线的辐射方向图、增益等天线的技术指标。最后对实际制作的天线进行测量，得到的结果与理论分析的结果相对比，天线在辐射方向上的吻合非常好，达到了设计的要求。

| Abstract: | This paper mainly discusses a uniform circular array antenna which has a circular reflect layer. Firstly it analyzes common uniform circular array antenna without reflect layer has been made based on directional theory, and the phase shift of antenna arrays can be calculated. Secondly the performance of circular array antenna with a reflect layer has been calculated based on mirror image theory,such as radiation pattern and gain. In the last of paper ,the result of testing of antenna which be made contrast with theoretic. It has a good inosculate in the direction of radiation. |
