摘要 采用以Rao-Wilton-Glission(RWG)为基函数的矩量法推导了分层球状微带天线的阻抗矩阵计算公式.在计算探针和贴片连接处的阻抗矩阵元素时,通过一种三角形对拆分方式简化了矩阵计算过程,并通过替代避免线积分奇异问题.提取了源、场点位于同一层媒质和不同层媒质时并矢格林函数的渐进项,以加快格林函数无穷项级数收敛速度.计算了一副球状微带天线,输入阻抗计算结果与文献结果吻合良好,说明分析方法的正确性和有效性. Formulas for calculating the impedance matrix of microstrip antenna in a multilayered spherical media using Rao-Wilton-Glission (RWG) basis functions based on MoM are derived. Division of pairs of triangles is adopted to cMculate the elements of impedance matrix at the junction of the probe and patch. The complex line integral singularity can be avoided by substitution. Asymptotic items of the dyadic Green's functions of the source and field points located on the same and different layers are extracted to accelerate convergence of the infinite series. The characteristic of a microstrip antenna in a multilayered spherical media is calculated. The results of input impedance are in good agreement with the published data, showing validity of the analysis method.
