Abstract :
We clarified a coupling mechanism through the air of electromagnetic noise generated a LSI mounted in the printed circuit board to the antenna coaxial cable placed in the same digital device. It is quantified with experiment and numeric simulation that how much noise power can be transferred to the coaxial cable and its terminal ends. Shield characteristics of the coaxial cable placed near a noise source is also examined and presented interesting results that will be usable for product design.
