Advanced computational tools for phased array antenna applications

This paper investigates the applicability of various Computational Electromagnetic (CEM) Methods for the design and analysis of phased array antennas. The full-wave methods like the Method of Moments (MoM), Finite Element Method (FEM), Finite-Difference Time-Domain (FDTD) and Multi-level Fast Multipole Method (MLFMM) are discussed in detail starting with simple arrays like a planar strip dipole to more complex Vivaldi antenna arrays. The usefulness of special features like the Periodic Boundary Conditions (PBCs) and the Domain Green's Function Method (DGFM) is also investigated.
