Investigation of the Effectiveness of RF Absorbers for Mitigation of Automotive Radiated Emission by Measurement and Simulation

Integrated circuit (IC) and printed circuit board (PCB) electromagnetic (EM) modeling methods are becoming essential during the development of automotive electronic control units (ECUs). Academic and industry efforts focus on radiated and conducted emissions from ICs and PCBs. Recent research proposes methods for modelling the far field radiated emissions of ICs and PCBs from near-field data, but this is a very complex problem and dependent upon many factors, often unknown. In this paper, the effectiveness of RF absorbers for the mitigation of radiated emission (RF) at GPS and GLONASS bands according to US automotive OEM requirements is investigated by modeling and measurements.
