Study on the Aperture Leakage EMI Problems and its Simulation

Abstract:

In the design and production process of car’s electronic equipment, the SE of the shield is reduced greatly for the existence of aperture.There is a modeling analysis to the aperture leakage EMI problems and derived a numerical calculation formula of the SE influenced by aperture leakage based on the slot antenna theory, also put forward the way to increase the SE of the shield by using Matlab software to simulate the SE of the shield with three regular apertures in different interference frequency. The simulation results have universal utility and which can provide data support for the design and layout of car’s internal circuits and devices.
