This paper analyze the effect of resonance of power/ground planes on the characteristic of the via discontinuity. The calculation of characteristic of via discontinuity from de-embedding technique is an efficient and fast method. But, the effect of the via location on the via discontinuity characteristic must be taken into account because there are resonances of power/ground planes in multilayer PCBs...
A new analytical formulation is presented for the shielding effectiveness of an enclosure with a dielectric-backed aperture and an inner PCB. The PCB is modelled as a conducting plane and its characteristic analyzed by Galerkin??s method.
In case of a portable multifunction terminal, the performance of one function can be degraded due to the emitted noise from a PCB trace of another function. In this paper, the electric field intensity around PCB edges emitted from a PCB trace is simulated by changing the location of the trace and allowing the variations of the ground pattern using a commercial electromagnetic solver for a DMB receiver...
