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.

• 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。
