| 摘 要： | 设计了一款适用于高频地波雷达的发射天线,通过顶部加载螺旋线圈的方式实现了天线电小化,且利用参差调谐原理,同时在顶部加载两个不同长度螺旋线圈,使天线实现双频谐振。该天线电尺寸仅为0. 085λ,且兼顾双频段和高效率的优点。利用CST电磁仿真软件进行仿真设计并制作缩比模型进行验证,仿真与实测结果吻合良好。

| Abstract: | Due to the low operating frequency of HF surface wave radar, the required antenna and array scale are large. Therefore, a dual-frequency transmitting antenna with small size is proposed in this paper. By loading the coil on top of the whip antenna, the antenna can be miniaturized. And the dual-frequency is realized when the two coils with different turns is loaded simultaneously. According to the consistency between the simulation results and measured results, it is proved that the antenna has the advantages of small size, dual-frequency and high efficiency. |
