| 摘 要： | 从混合位积分方程出发,采用矩量法结合曲线分段的三角基函数和脉冲检验函数分析了阿基米德平面螺旋天线,给出了输入阻抗,电流分布以及辐射方向图结果.从曲线形式的海伦积分方程出发结合折线分段的脉冲基函数点匹配法比较结果与文献2～4]十分吻合.由于采用了曲线分段,在相同分段数情况下其结果的精度将比采用折线分段的高.

| Abstract: | In this paper, Archimedean spiral antenna is analyzed using a mixed potential integral equation, and the equation is solved by the moment method incorporating with curved piecewise triangle sub-domain basis and pulse testing functions. The numerical results of input impedance, current distributions and radiation patterns of Archimedean spiral antenna are presented and have good agreement with the published results in 2-4], where piecewise segmentations were adopted. Since the curved basis and testing functions can exactly follow the contour of the spiral antenna, the accuracy of the results obtained with curved segmentations should be better than the results with linear segmentations. |
