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,利用FDTD方法研究了在平面波激励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场不仅与口径形状有关还与所加激励源的极化方向有关,即口径窄边与激励源极化方向一致时,辐射场幅值最大。实验分析表明该方法的有效性。 Ringing in the antenna, antenna bandwidth and the capability of radiating a undistorted pulse are important parameters for applications in the field of ultra-wideband antenna. The FDTD numerical method is used to describe the relation between the radiated waveform in E-plane and H-plane and the width of pulse under different size and shape of the aperture as a plane wave incident upon the aperture.
