Fast Numerical Analysis of Finite Arrays of Antennas in Finite Dielectric Volumes

This paper presents a formulation for the fast analysis of finite arrays of antennas embedded in finite dielectric volumes. The Method of Moments system of equations is reduced with the help of a Macro Basis Functions approach; this reduction is accelerated with the help of a multipole formulation. Fast pattern evalulation is carried out with the help of a FFT-based approach. Comparisons with full-wave solutions are shown for broadband dipoles embedded in dielectric spheres.
