摘要
为了在短波频段内实现天线的小型化和宽带工作特性,采用遗传算法和矩量法相结合的优化算法,对鞭状天线的集总加载元件值、位置以及匹配网络参数进行优化筛选。同时在满足性能要求的前提下,选择较少的加载点数目和加载电路中元件个数,以便于天线的加工制作和实验调整。最后,制作了一付样品天线。经测试,仿真结果与实测结果吻合良好,表明该天线在较宽的频带内达到了满意的阻抗特性和方向图特性。
In order to realize the shortwave antenna miniaturization and broadband characteristics, using a genetic algorithm and MOM combined with the optimization algorithm, the whip antenna is lumped loading element value, position and the matching network parameters are optimized screening. At the same time to meet the performance requirements of the premise, choosfng the less loading points and load circuit element number, to facilitate the manufacture and experiment of antenna. Finally, making for a sample antenna. After the test, simulation results are in good agreement with the measured results, show that the antenna in a wide band achieved satisfactory impedance characteristics and pattern characteristics
