Abstract

An efficient technique is presented, based on the application of a multi-resolution (MR) approach to the BMIA/AIM formulation. The BMIA/AIM is an extension of the banded matrix iterative approach (BMIA) to a non-canonical grid by using the adaptive integral method (AIM) and allows an efficient analysis of patch antennas having medium/large or large dimensions. The multi-resolution (MR) approach keeps the different scales of the problem directly into the basis functions representation. The basis is constructed via the "dual-isoscalar" technique, which possesses both spectral and spatial resolution, and allows us to considerably improve the MoM matrix condition number and iteration convergence.
