Finite Antenna Array Analysis with a Unit Cell Domain Decomposition Method - Application Brief

ANSYS has developed an efficient iterative domain decomposition-based finite element technique for modeling repetitive antenna arrays. The scheme leverages the repeating nature of an array to minimize the setup time for the domain matrices and the amount of computational resources required for a solution. Comparison results between this technique and an explicit FEM solution are presented along with a solution performance for a 1,024- element dual-slant polarized Vivaldi array.
