Sažetak
In this paper a fast moment method algorithm is developed to compute the scattering properties of large but finite strip array on a dielectric slab. Exact spectral Green's function is used to derive electric field integral equation (FFTE) for the field on the strips. In the solution process closed form asymptotic expressions are derived for mutual coupling terms for strips separated by 0.1 free-space wavelengths or more. This, coupled with the interpolation technique used for the impedance self terms drastically improves the computational speed and efficiency of the moment method solution for the strip current density. To validate the developed algorithm, extensive tests have been done for both, TE and TM incident polarization, for strips loaded with dielectric slab with or without ground plane or placed in the free space. Obtained results are in a very good agreement with the data in the open literature. Since this algorithm is very fast compared to other conventional methods, it can be used to analyze very large strip arrays in the Ultra-Wideband (UWB) frequency range.
