Mixed Order Tangential Vector Finite Elements (TVFEs) for Tetrahedra and Applications to Multi-Functional Automotive Antenna DesignAbstract
Mixed order tangential vector finite elements (TVFEs) of order 0.5, 1.5, and 2.5 for tetrahedra are presented and used in conjunction with an exact Finite Element-Boundary Integral (FE-BI) formulation. The main advantage of using mixed order elements is to reduce the computational complexity when solving large problems. As an illustrative example, a wide band antenna is designed and placed on an automobile. Results regarding the antenna return loss, far field pattern, axial ratio, and gain are presented.
