摘　　要：对于金属载体上的线天线,采用RWG基函数以及伽略金法将电场积分方程转化为矩阵方程组,结合稳定双共轭梯度法,解算出表面电流的展开系数,进而得出金属载体上线天线的辐射特性。为了验证算法的正确性,以金属载体附近的单极子天线为例,采用MOM(mehtod of moment)法以及软件FEKO进行仿真计算,两种方法的计算结果验证了算法的正确性。For wire antenna nearby metal carrier, the electric field integral equation was converted to a matrix equation based on RWG basis functions and Galerkin method, combined with bi-conjugate gradients stabilized method. The expansion coefficients of surface currents were calculated, then the radiation characteristics of wire antenna were got on metal carrier. In order to verify the correctness of the algorithm, a monopole antenna nearby metal carrier was calculated by MOM and FEKO software. The results of two calculating methods all show the correctness of the algorithm.
