Computed field distributions within a passenger vehicle at 2.4 GHz

Numerical simulation has been carried out to assess the effects of different source antenna locations on electric field distribution within a vehicle cabin at 2400 MHz. Only fixed onboard antennas mounted within the vehicle cabin are considered. The car model contains only metallic parts and ignores dielectric furnishings. Localised electric field visualizations within the vehicle cabin are obtained using simulated 2D cut-planes. They are complemented by histograms describing the distribution of electric field amplitudes within the vehicle cabin volume relative to a 1W power source. The averaged electric field levels obtained were used to compare the effectiveness of the source antennas placed in various locations within the vehicle.
