PROJECT TITLE :

A Novel Shielding Effectiveness Matrix of Small Shield Cans Based on Equivalent Dipole Moments for Radio-Frequency Interference Analysis

ABSTRACT:

A definition of a shielding effectiveness (SE) matrix for tiny protect cans used to suppress intra-system noise coupling in mobile devices is proposed. Assuming protect cans enclosing a noise supply can be modeled as equivalent dipole moments along with integrated circuits (ICs), a replacement SE matrix for radio-frequency interference analysis is defined as a ratio of equivalent dipole moments with and without a shield will. The equivalent dipole moments are experimentally extracted employing a GTEM cell and 2 sorts of probes (monopole and loop), that mimic well the radiations of ICs. Furthermore, the estimation of suppression of noise coupling to an antenna using the proposed SE matrix is successfully validated through numerical simulations.
