Problem Description

The demand for electromagnetic simulation in the automotive industry is increasing as communication demands in the industry becomes more varied and complex. Keyless entry and engine ignition systems, bluetooth integration of mobile phones with vehicle audio systems, GPS receiving antennas, proximity radars, AM-FM and TV antennas integrated into windscreens and highly complex cable paths are just some of the requirements that leading vehicle designers have to satisfy.

Fundamental problems that engineers have to solve and optimise include antenna placement, electromagnetic compatibility (EMC) analysis and radiation hazard analysis. Modern electronic and wireless technologies are continually moving to higher transmitting frequencies as the lower frequency spectrum becomes more congested. Model analysis at these higher frequencies imply larger and more complex meshes.

FEKO Solution Scope

Typical applications of FEKO's technology in the automotive industry include:

• Antenna placement optimisation for GPS receivers, GSM transceivers and collision avoidance radars.
• Rigorous analysis of integrated, multilayer glass windscreen antennas.
  
• EMC analysis for arbitrary cable bundles and cable paths in a vehicle, minimising crosstalk or communication interference between different cables.
• Radiation hazard analysis to ensure occupant safety with regards to harmful radiation.

 Key FEKO Technologies

• The Multilevel Fast Multipole Method (MLFMM) which enables simulation of electrically large structures.
• Hybridisation of the Method of Moments (MoM) with the Finite Element Method (FEM) for radiation safety analysis or the analysis of the effect that vehicle occupants have on RF signals.
• Windscreen antenna modelling method which requires that only the antenna elements are meshed, while accurately modelling all layers of glass, as well as the curvature and finite size of the windscreen.
  
• Simple cable coupling analysis with FEKO, for several predefined coaxial cables along arbitrary cable paths.
• An interface to dedicated cable modelling software (either CableMod or CRIPTE) allows for the analysis of complex cable bundles along arbitrary cable paths.
