摘　　要：叙述了矩量法(MOM)结合渐近波形估计(AWE)技术快速求解天线宽带输入阻抗的一般步骤,并将AWE技术拓展应用到阵列方向图的求解中。AWE技术的计算结果与经典矩量法计算的结果和SuperNEC的仿真结果比较,三者吻合很好,从而证明了该方法的精确性,同时也显现出了渐近波形估计技术可以大大减少计算时间的优势。The method of moments （MOM） in conjunction with the asymptotic waveform evaluation （AWE） technique to calculate the wide-band input impedance fleetly is depicted briefly. And then the application of AWE technique is expanded to calculate the antenna array pattern. The results of AWE are well agreed with those of MOM and SuperNEC, which proves that the method is accurate in this paper, and also shows that the AWE technique can decrease the computing time greatly.
