Modeling and EMC simulation of vehicular radio transmission antenna

Abstract

This paper presents an average complexity model of a military vehicle (Humvee) carrying a radio transmission antenna for the Electromagnetic Compatibility (EMC) simulation by using the Finite Difference Time Domain method (FDTD). Electromagnetic (EM) fields inside and nearby of the vehicle are computed. The high strength EM fields locations called hot-spot inside the cabin are investigated. Surface current on the metallic structure of the vehicle is estimated. Then the EM exposure is compared with the recommended limits defined by the RE102 directive.
