摘要 使用矩量法分析研究了有限曲面微带天线的结构散射特性。运用等效原理,建立了一般曲面微带天线的体面耦合电场积分方程,在积分方程中由于采用的是自由空间格林函数,从而避免涉及微带天线分层介质格林函数的解析表示和精确计算。在伽略金法中,介质部分采用SWG基函数,金属表面部分采用RWG基函数,通过金属表面与介质基片交界面处施加电流连续性方程,有效地减少了待求未知量数目,明显改善了阻抗矩阵条件数。 Structure scattering analysis of microstrip antennas mounted on a finite curved surface is presented via method of moments.Using the equivalence principle,the coupled volume-surfaced integral equation of arbitrary curved surface conformal microstrip antenna is formulated,in which the free space Green＇s functions is used so as to obviate the analytic expressions and accurate computation of the dyadic Green＇s functions.In Galerkin method,the SWG and RWG basis function are used for the dielectric and the conductor surface respectively.According to the continuity equation of electric current on the interface between conductor and dielectric,an efficient scheme is proposed to reduce the unknown numbers and condition numbers of the matrix equation.
