摘要

由于越来越多地使用无线通信设备，高频噪声问题变得越来越重要。在这项研究中，石墨烯薄膜被用作高频功率吸收器。环氧树脂与石墨烯混合以调节其导电性。通过丝网印刷技术将石墨烯薄膜沉积在FR4衬底的微带线上。实验结果表明，石墨烯薄膜的片电阻为114 Ω/sq，电导率为973 S/m，在1.35 GHz时功率损耗达到70%。

Absorption of High-Frequency Power by Using Graphene Films

As a result of the growing use of wireless communication devices, high-frequency noise issues are becoming increasingly important. In this study, a graphene film is utilized as a high-frequency power absorber. Epoxy is mixed with the graphene to adjust its conductivity. The graphene film is deposited onto a microstrip line of FR4 substrates via screen printing technology. Experimental results show that graphene film is with a sheet resistance of 114 Ω/sq and a conductivity of 973 S/m and its power loss reaches 70% at 1.35 GHz.
