The exact model of an antenna array with a dielectric radome is established by using the surface integral equations and method of moments (SIE-MoM). The proper preconditioning techniques (PT) and the fast multipole method are employed, which obviously improves the property of the MoM matrix equation, reduces the memory occupation and accelerate the iteration convergence of the conjugate gradient (CG)...
In this paper, based upon the equivalent principle and surface integral equations, the exact model of an antenna and dielectric radome structure is established by using method of moments (MoM). The equivalent strip-model is used for the thin wire antenna, in order to alleviate the singularities in the meshing process. The ill-conditioned MoM matrix is improved by the preconditioning technique. The...
