| 摘 要： | 基本的单极子天线由于其本身的特社会在天线内部对馈入的信号进行多次反射，严重,制约着它的辐射性能。采用时域有限差分法对比计算了加载与非加载单极子天线的时域辐射特性。计算结果表明，加载是改善单极子天线时域辐射性能的最佳选择，但需要以牺牲辐射效率为代价。

| Abstract: | According to the specific characteristics of monopole antenna, feeding signal may be multi reflected at the terminals, which could seriously damage the radiation characteristics. Therefore the time domain characteristics of loaded monopole antenna are calculated and analyzed using FDTD method. Compared with the numerical results of unloaded monopole, antenna loading exhibits its effectiveness to improve the general ultra narrow pulse radiation characteristics. But this improvement is accompanied with the loss of radiation efficiency. |
