摘　　要：该文介绍了一种小型高效的短波宽带天线,天线采用线栅型扇锥结构,运用矩量法对不同导线数量、馈电端间距、扇锥张角下天线电压驻波比和最大增益进行仿真计算,并根据仿真结果制作出实际天线,测试结果与仿真结果较好地吻合。天线在3～30MHz频段95%以上频率点驻波比小于2,平均辐射效率达到98%,平均增益超过6dBi。A small size and high efficiency HF broadband antenna that use wire sector-conicai structure is designed, The Method of Moment is used to compute the VSWR and power gain of the antenna with different wire number, different size of feed-point gap and different sector-conicai open angle. A sample antenna is built base on simulation results. The measured VSWR and radiation pattern agree well with those from simulation, The VSWR is within 2：1 over more than 95% of HF band, the average efficiency is 98% and the average gain is greater than 6dBi.
