中文摘要: 介绍了一种用于 S 波段（2~4 GHz）探冰雷达的高增益 Vivaldi 天线。天线选择介电常数 3.48 的ROC4350B为介质板材料，采用微带馈电线转槽线的耦合结构进行馈电，并在辐射臂两侧加载两段指数型开槽提升整体增益，在渐变槽线中间加载指数型引向器进一步提升天线辐射性能。仿真优化后天线总体尺寸为113.6 mm×85.0 mm×1.52 mm。仿真结果表明，天线在S波段内回波损耗S₁₁< -10 dB，天线增益整体在5.39 dB以上，最高达到了9.6 dB，且增益曲线平滑，实测结果与仿真结果较为吻合。

Abstract:A high gain Vivaldi antenna for S-band（2~4 GHz）ice detection radar is designed. The antenna is made of ROC4350B with a dielectric constant of 3.48 as the dielectric plate material. The coupling structure of microstrip line to slot line is used for feeding，and two exponential slots are loaded on both sides of the radiation arm to enhance overall efficiency. An exponential directional device is loaded in the middle of the gradient slot line to further improve antenna radiation performance. After simulation optimization，the overall size of the antenna is 113.6 mm×85.0 mm×1.52 mm. The simulation results show that the antenna operates in the S-band S₁₁< -10 dB，the overall antenna gain is above 5.39 dB，reaching a maximum of 9.6 dB，and the gain curve is smooth. The measured results are in good agreement with the simulation results，and the antenna pattern symmetry and end emission characteristics are good.
