Abstract :
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) method. Based on the validation of the correctness of the algorithm, some wire antenna arrays with dielectric radomes are numerically simulated, and their radiation characteristics are analyzed.
