| 摘 要： | 介绍了一种圆极化宽带圆锥喇叭天线，用于地检设备子系统中。天线的圆极化性能是通过金属螺钉在圆波导的管壁对称地插入，等间隔排列来实现的，螺钉直径与插入深度由计算得出。为实现信号低反射馈入，馈电端口采用了矩一圆波导转换器，完成了从矩形波导过渡到圆形波导。天线的辐射器采用了传统的圆锥喇叭。使用CST微波工作室。仿真该天线，并调整各部分的尺寸，使得天线性能最优化。实验测量数据与仿真结果吻合较好，在400MHz的工作带宽内，天线增益大于14．5dB，增益平坦度好，轴比小于1．5dB，驻波比小于1．2。

| Abstract: | A circularly polarized antenna is introduced.The design of the antenna is based on practical need for a type of satellite ground checkout-system.The circular polarized field is realized using metal screws inserted in circular waveguide and equally spaced.The diameter and depth of the screws are theoretically analyzed.For low signal reflection,rectangular to circular converter is used in the excitation port.Conic horn is used for radiation.The antenna is simulated using CST microwave studio.By adjusting the ... |
