摘　　要：由于探地雷达系统大多采用超宽带窄脉冲信号,因此要求天线具有极宽的工作带宽。利用矩量法对线性离散电阻加载蝶形天线进行分析,结果表明,线性离散电阻加载在使天线获得宽带特性的同时,并使辐射的脉冲信号拖尾变得平稳,因此能够满足探地雷达系统的需要。The ground penetrating radar （GPR） system usually uses ultra- broadband short pulse, so the antenna must have a wideband. The bowtie antenna with linear discrete resistor loadings was analyzed in this paper by using the method of moments. The result shows that, with such a loading form, the antenna can get a wideband and the radiated short pulse can have a flat tail. The antenna can therefore be applied to the GPR system.
