Summary:
Evaluation of electric fields inside and outside a car is strongly needed, when wireless communication systems are employed in a car. In this paper, electric field distributions in a car are clarified through calculations and measurements. A 1/3 scale down model is employed. Used frequency is 2859MHz that is 3 times of 953MHz. An optical electric field probe is employed in measurements so as to minimize disturbances caused by a metallic feed cable. By a method of moment simulator utilizing the multilevel fast multipole method scheme, calculations are performed on a personal computer. This scheme achieves lightning of calculation times and memories. In comparisons of measured and simulated results, very good agreements are achieved. As a result, accuracies of measured and calculated results are ensured.
