In this paper radiated EMI diagnosis and noise modeling for cellular phone is proposed. With this method, the radiated EMI noise mechanism models of the cellular phone are introduced, and changing tendency of the wave impedance with the distance is described to diagnosis the radiated EMI noise type of the cellular phone. It is shown from the experiments that the proposed method is a fast and efficient...
In the paper, a new approach by using near-field probes is proposed to identify mechanism of radiated EMI noises, i.e. CM noise and DM noise, according to but only the internal relationship between radiated EM field and near-field wave impedance, but also the inner relationship between wave impedance and measurement distance. Then, radiated EMI noises decrease obviously after suppressed by using 3-m...
