Numerical simulation approaches for the development of automotive antenna systems

One challenge of automotive antenna engineering is to make important decisions concerning the antenna performance and the complete EMC aspects for the complete car at an early stage of development [1]. The focus of the presented paper is related to different numerical methods to present a solution for virtual antenna development. Multiple automotive antennas operating in various frequency ranges are presented. The frequency ranges used start from some kHz up to approximately 100 GHz. The computation of the electromagnetic characteristics of the different antennas requires the solution of Maxwell´s equations. In several problem cases, the solution is achieved using different numerical approaches as shown in this paper. Deploying numerical techniques, radiation and scattering problems can be calculated.
