Summary:
3D Hybrid Finite Element - Finite Difference Time Domain (FE/FDTD) Method is developed and applied to the numerical modeling of antennas. The antenna geometry is modeled using tetrahedral finite element mesh. Pyramidal elements are introduced in the transition from unstructured tetrahedral elements to structured hexahedral elements. The finite element formulation incorporates the excitation of antennas using coaxial line or stripline ports with Transverse Electromagnetic Mode (TEM). Computation of reflection coefficient of typical antennas is presented.
