摘　　要：利用平面波谱展开理论和时域有限差分法对几种典型天线的远场方向图建模计算 ,分析和比较了不同采样平面对远场的影响 ,以及平面波谱理论对强、弱方向性天线的适用性 ,为进一步误差分析修正奠定了基础。The far field patterns of several types of antennas had been discussed by means of PWS and FDTD methods respectively. And through the comparisons of results, we analyzed the effects of sampling plane to far field, demonstrated the applicability of PWS theory to high and low directivity antennas , so that we can further researchthe error analysis and correction.

关 键 词：平面波谱展开 时域有限差分法 时域近场测量
