摘要：

EMI shielding means blocking electromagnetic radiation by using the material reflection and or absorption. Recently, carbon fiber materials have become alternative shielding materials due to their unique properties, including being lightweight, and having high strength and stiffness. This paper will study the performance analysis of twill CFRP with thickness variation as shielding material for electronic device applications in UHF, L- Band, and S-Band frequencies. EMI test was performed with the free-space method in the anechoic chamber. The S21 and S22 parameters give similar trends, which result in coarse fluctuation in UHF and L-Band frequency and stable curves in S-Band frequency. The absorption loss of CFRP with 2mm thickness has a higher value, while the reflection loss of both materials is the same. The values of average SET CFRP 1mm and 2mm thickness are -33.8 and -33.7 dB, respectively, which cannot fulfill the requirement value for electronic device applications.
