Abstract

The exact model of an antenna array with a dielectric radome is established by using the surface integral equations (SIE) and method of moments (MoM). The multilevel fast multipole algorithm(MLFMA) is used to reduce the memory occupation and accelerate the iteration convergence of the conjugate gradient (CG) method. Based on the validation of the correctness of the algorithm, some electrically large antenna-radome system are numerically simulated, and their radiation characteristics are analyzed.
