摘要
设计了一副双加载舰用短波宽带7m鞭状天线，建立了矩量法仿真模型，利用遗传算法优化了加载位置、加载网络参数和匹配网络参数，计算了天线的电压驻波比、增益和方向图。实际制作了一副天线并进行了测试，实测的电压驻波比和增益数据与仿真计算结果相吻合，在3．5～30MHz频率范围内天线驻波比小于3：1，在8～30MHz频率范围内平均增益大于2dBi。
A broadband twin-loaded whip-type antenna with 7 meters length worked at high frequency （HF） band is designed for shipboard use. A simulation model is established based on Method of Moment. The position of loaded network and the electric parameters of both loaded and matching networks are optimized using Genetic Algorithm, and the voltage standing wave ratio （VSWR）, gain and pattern are computed as well. A sample antenna is built and tested. The measured VSWR and gain agree well with those from simulation. The VSWR is within 3.1 over 3.5-30 MHz frequency range, and the average gain is larger than 2 dBi over 8-30 MHz.
