| 摘 要： | 介绍了C波段单层16单元矩形径向线螺旋阵列天线的模拟优化结果，对按照优化结构尺寸加工的天线模型进行了实验研究。在实验中，利用设计的用于连接标准接口和耦合输入口的阻抗变换器，采用标准线极化天线比较法对阵列天线辐射特性进行了测试。实验结果表明：在3.8～4.2 GHz的频率范围内天线增益大于17 dB，口径效率大于74%，天线轴比小于 1.3 dB，驻波系数小于1.2，与数值计算结果基本一致。

| Abstract: | The optimized simulation result of a C-band 16-element single-layered radial line helical square array antenna is presented and the experiment researches are developed for an antenna fabricated according to simulated structure. During experiment research, an impedance converter is designed to connect standard port with antenna port, and the method of comparing with standard linearly polarized antenna is used to measure antenna circularly polarized gain. The experiment result shows that, in the range of 3.8 GHz to 4.2 GHz, antenna gain is over 17 dB, aperture efficiency is over 74%, axial ratio is below 1.3 dB and antenna VSWR is below 1.2. It shows a good agreement with simulation result． |
