Synthetic function analysis of large printed structures: the solution space sampling approach

This work proposes an algorithm based on the numerical definition of entire domain basis functions to be used in the full-wave method of moments (MoM) solution for large printed antennas. After a block partitioning of the structure, entire domain basis functions are generated and then employed in the global solution process. The generation algorithm and a possible selection model is presented in detail. The method permits a strong reduction of memory occupation and computation time. A numerical example for a 4 /spl times/ 2 array of stacked patches is presented.
