摘　　要：在大多数脉冲电磁场的应用中，需要能在空间某一方向上产生最强瞬时冲击脉冲的天线，为了这一目的，本文中用时间步进法对曲线形状偶极子天线的时域辐射特性进行了分析，并在此基础上用共轭梯度法对天线的形状进行了优化。优化过程的目标函数为天线前向辐射脉冲的瞬时冲击值，优化变量为天线的形状参数。In most applications, the antennas which can generate maximum peak value of the radiating pulse in a certain direction are demanded. In order to meet this demand, the antenna shapes are optimized by the conjugate gradient method in this paper. The timedomain radiating characteristics of the dipole antennas are analyzed by the time stepping method. The objective functions used in the optimization procedure are the peak values of the radiating pulses in the front direction of the antenna, and the variables to be optimized are the parameters of the dipole shapes.
