【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。更多还原

【Abstract】 The transmitting antenna suitable for high frequency surface wave radar was designed. The antenna was electrically minimized by loading helical coils on the top,and two helical coils of different lengths were loaded on the top at the same time to achieve dual frequency resonance. The antenna have an electrical size of only0. 085λ,the advantages of dual frequency and high efficiency. CST MWS software was used to simulate the design and a scaled model was produced for verification. The simulation is in good agreement with the measured results.更多还原
