摘　　要：提出了一种新型三线式宽频带短波基站天线的详细设计过程,对天线进行了仿真分析和实际测试,该天线在2 MHz^30 MHz频带范围内满足电压驻波比小于2.0,相对增益可达3 dBi^5 dBi,比普通宽带短波基站天线工作频带宽、辐射效率高。而且适应于不同用途,三线式短波基站天线具有平拉和倒‘V’两种架设方式。The design process of a new kind three-line wide band HF base-station antenna is proposed.And the antenna is simulated and practically measured.Its VSWR of the 2 MHz^30 MHz frequency band is below 2.0,and its relative gain can arrive at 3 dBi～5 dBi.So its bandwidth is wider than the traditional wide band HF station antenna,and its radiation efficiency is also higher than it.To be fit for difference usages,this antenna has two setting-up methods: horizontal and inverted V.
