FEKO-Based Method for Electromagnetic Simulation of Carcass Wires Embedded in Vehicle Tires

Abstract

In a tire pressure monitoring system in which a pressure censor and a transmit antenna are contained in a tire, electromagnetic simulations of radiations from carcass embedded tires are requested. However, it is difficult to accurately determine these shielding effects. In this study, methods for performing accurate electromagnetic simulation by adopting the MoM scheme are determined. In the study of the electric fields inside a tire, calculated results are compared with the theoretical distributions in a coaxial cylindrical resonator. In the case of a dense carcass arrangement, simulation results are in good agreement with theoretical results. In the study of electric fields penetrating carcass wires, the results of the MoM scheme are compared with those obtained using the finite element method (FEM). The adequate mesh size of the tire rubber in the MoM scheme for which the accuracy of the simulation results is guaranteed is established. Finally, electromagnetic simulations of an actual carcass tire model are performed.
