Abstract

This document presents the application of a new electromagnetic in-house parallel EM simulator to the antenna analysis. The simulator is included in the commercial software HOBBIES. HOFEM makes use of a weak formulation based on double curl vector wave equation discretized with the higherorder isoparametric curl-conforming tetrahedral and triangular prismatic finite element rigorous implementations of Nedelec's first family of elements. These implementations together with an appropriate hp-adaptivity technique provide very accurate field approximations. A non-standard mesh truncation technique, FE-IIEE (Finite Element - Iterative Integral Equation Evaluation) for open region problems is also implemented providing an arbitrarily exact radiation boundary condition while retaining the original sparse structure of the FEM matrices. A numerical example is presented showing the reliability, performance and versatility of the solver for the antenna analysis.
