Abstract

In order to design reflectarray antennas within reasonable CPU times, fast and accurate numerical tools for the analysis of periodic multilayered structures are required. In this paper, we compare two of these numerical tools: the spectral domain method of moments based on multilayered Green?s functions (SDMOM-MGF) and the spectral domain method of moments based using matrix scattering generalized (SDMOM-GSM). Although both techniques are very similar, it is shown that the SDMOM-MGF is faster than SDMOMGSM in the cases where very thin layers are present in the multilayered substrate. Also, in this paper we compare two sets of basis functions for the current density on periodic arrays of rectangular patches embedded in multilayered media. It is shown that basis functions fulfilling the edge condition are more convenient than the sinusoidal basis functions concerning memory and CPU time savings, especially when the dimensions of the patches are close to the dimensions of the periodic unit cell.
