Abstract :
In this paper, the edge current phenomena of on-board antenna, PIFA, are simulated by full 3D EM simulator, GEMS of 2COMU. The simulation of current density interprets the current crowed effect which makes a sensible explanation for the occurring of EMI noise even if the differential PCB layout topology is obtained for signal trace routing. Bridge connection, a solution for diverting this EMI current under this circumstance is also presented by simulation and real case verification in this paper.
