Accuracy in modeling conformal window glass automotive antennas by EM numerical solvers

This paper deals with the issue of the accuracy in modeling conformal automotive glass antennas operating across the FM band. A monopole antenna embedded in the side glass window of a stylized full-scale car model is analyzed using both frequency domain “source method” and time domain “field method” electromagnetic (EM) solvers. Numerical results are compared with measurements made in a far field open range on a physical model identical to the virtual one, in order to cross-validate EM simulations and measures.
