摘要: A rigorous formulation in the spectral domain is used to investigate radiation from printed traces on a circuit board frequency range 30 MHz 1 GHz. The coupling effect among adjacent and shielding effectiveness of metallic coating plastic cover are analyzed. It found that around resonant frequencies critical satisfying FCC (US Federal Communications Commission) requirement, an appropriate can resolve problem. >
