Validation of predicted 3D electromagnetic field distributions due to vehicle-mounted antennas against measured 2D external electric field mapping

Predicted 3D electromagnetic field distributions from TLM models of two vehicle-mounted antenna installations are compared with 2D measurements for similar systems over four horizontal planes. Sample qualitative (visual) comparisons provide useful insights into the sources of some of the differences between the models and the measurements. Quantitative measures show that these differences are within the measurement uncertainty for more than 83% of the points for a roof-mounted antenna, and for more than 70% for a wing-mounted case. These results are considered to be excellent, given the known disparities between the measured and simulated systems
