摘　　要：如何高效而又有较少拖尾的将信号辐射出去是超宽带天线的设计关键 ,本文利用FDTD方法研究了TEM喇叭 ,得出喇叭的形状和激励脉冲的脉宽对TEM喇叭的传输波形的影响。Ringing in the antenna,antenna bandwidth and the capability of radiating an undistorted pulse are important antenna parameters for ultra-wideband antenna .In this paper the FDTD numerical method is used to study the feature of TEM horn and its influence on the transmitted waveform can be obtained by studying the shape of the horn and the width of pulse.

关 键 词：FDTD 超宽带天线 TEM喇叭 高斯脉冲 传输波形
