Measured Impact of Seats and Glazing on the Coupling of Electromagnetic Fields into Vehicles and Their Wiring Harnesses

Whole vehicle electromagnetic models are desirable to allow automotive EMC and antenna engineering issues to be analysed during the design stages of vehicle development. However, models of this scale and complexity can require very significant model development and computing resources. Thus, opportunities for limiting the scope of such models are of considerable importance in ensuring that this type of analysis is practicable. Measurements have been carried out on a complete vehicle to assess the impact of common components such as the seats and window glazing. The results suggest that these components could be neglected in many models without introducing significant errors.
