摘　　要：针对基于海上浮标的短波鞭状发信天线带宽窄、阻抗变化剧烈的特点,建立了直立鞭天线和螺旋鞭天线的仿真模型,并研究了天线的反射系数和阻抗特性。主要对比分析了不同导线半径、不同螺旋匝数和不同分布加载方法对天线电气性能的影响,最后给出了天线设计方案:天线高度6m,天线导线半径5mm,天线螺旋半径10cm,绕制方式为0~3m为直立导线、3~6m正向绕制5匝导线。该方案实现了天线在短波频段5~30MHz输入阻抗变化平缓且低频段输入电阻较大易于匹配。Aiming at the disadvantages of the short wave whip signaling antenna’s narrow bandwidth and high impedance changes based on sea buoy,the simulation model of the vertical whip antenna and the spiral whip antenna was established,and the reflection coefficient and impedance characteristics of the antenna were studied.The influence of different wire radius and different spiral turns and different distribution loading methods on the electrical performance of the antenna was chiefly analyzed,and finally,the plan of the antenna was provided:the height is 6 m,the wire radius is 5 mm,the screw radius is 10 cm,the winding mode is that a vertical wire is connected between 0 and 3 meters and a five turn wire is being wound in the positive direction between 3 and 6 meters.The plan achieves that the input impedance change of the antenna in the short wave band of 3~30 MHz is gentle and the input resistance of the low-frequency segment is larger and easier to match.
