摘要
设计了一副带尾翼和集总电阻加载的短波宽带三角形偶极子线天线。采用矩量法(MoM)对该天线的电特性进行了仿真计算,优化了天线的电压驻波比和增益特性,并制作了一副实验天线。数值仿真和测量结果表明:在3～30 MHz频带内,该天线电压驻波(VSWR)比小于2.2,在一般地面上平均增益大于4 dBi。
A broadband HF triangle dipole wire-antenna with tailed wings and lumped loading resistors is designed and analyzed by using method of moments （MoM）. Its voltage standing wave ratio （VSWR） and gain are optimized. An experimental antenna is made. Both numerical results and measured data show that the VSWR is less than 2.2 and the average gain for the average ground is larger than 4dBi in 3-30 MHz frequency range.
