小型短波宽带鞭天线研究

Small Shortwave Whip Antenna Broadband Research

设计了一副用于天线阵列的5 m鞭状天线,综合运用了集中加载和顶负载的方法,降低了天线阻抗对频率的敏感程度,采用矩量法和遗传算法对加载网络的数量、位置、加载元件阻值进行优化设计,实际制作的天线测试结果与仿真结果基本吻合,测试结果表明天线的驻波比在5~20 MHz频率范围内小于2.5。

It is designed a pair of 5 m whip antenna for antenna arrays, the integrated use of a centralized method of loading and top loading, which is reducing the sensitivity of the antenna impedance versus fre- quency and using the moment method and genetic algorithm to load the network number so that the location load resistance element can be to optimize the design, and the actual production of the antenna test results are consistent with the simulation results, and the test results show that the antenna VSWR within 5 - 20 MHz frequency range of less than 2.5.
