球状微带天线分析中细条带馈电模型的构建

内容简介：通过引入半 RWG（Rao-Wilton-Glisson）函数以及边界电荷，成功解决了细条带馈电模型问题。结合矩量法，具体分析了电流源以及电压源模型中阻抗矩阵 Z 以及V 矩阵，并且巧妙解决了边界处自阻抗元素的线积分奇异性问题。这两种馈电模型分别用于分析球状微带天线的输入阻抗以及远区场特性，计算结果与文献[13]结果一致，验证了这两种馈电模型的准确性和有效性。

Abstract：The problem about the thin strip feed model is solved successfully by introducing the half Rao-Wilton-Glisson (RWG)function and boundary charge.The impedance matrix Z and matrix V in the current source model and voltage source model are analyzed in detail based on the method of moments,and the line inte-gral singularity problem in calculating self impedance elements at the boundary is settled skillfully.The two feed models are used to analyze the characters,such as input impedance and far field of spherical microstrip anten-nas,and calculated results agree with those from literature [13],which shows the validity and effectiveness of the two feed models.
