Abstract

An efficient technique based on the extension of the banded matrix iterative approach (BMIA) to a not canonical grid by using the adaptive integral method (AIM) is presented for the analysis of stacked patch antennas of large dimensions. The patches can have arbitrary shape and orientation and are modeled with subdomain triangular patch basis functions. The method allows us to use a FTT-CG scheme reducing the CPU time per iteration to O(N log N) and the memory requirement to O(N). Therefore, the approach is suitable for solving large-scale problems on a small computer.
