| 摘 要： | 如何高效而又有较少拖尾地将信号辐射出去是超宽带天线的设计关键，本文利用FDTD方法研究了在口径面上设定场值的情况下口径形状和激励脉冲的脉宽与辐射波形之间的关系，得出在不同口径形状的情况下口径辐射的两个主轴面的辐射情况。

| Abstract: | Ringing in the antenna, antenna bandwidth and the capability of radiating a clean pulse are important parameters for the design of ultra wide-band antenna .In this paper the FDTD (finite-difference time-domain) numerical method is used to study the relationship between the radiated waveform, the shape of aperture and the width of pulse under the condition of given source in the aperture. The radiated waveform in E-plane and H-plane for different aperture shape is obtained. |

| Keywords: | ultra wide-band antenna FDTD aperture Gauss pulse |
