Résumé / Abstract
The emission measurements on-board train requires better understanding of certain interference sources, and notably of interferences due to the losses of contact between catenary and pantograph. This paper then presents a modeling methodology to analyze the effect of pantograph arcing on GSM-R antenna on the train roof. The model was realized with CST microwave studio and comparisons were performed with experimental results to assess the quality of the numerical results. Finally, simulations were carried out in order to discriminate the couplings between the GSM-R antenna and the different components of the model.
