EMC (Electro-Magnetic Compatibility) issues are becoming more and more significant in the integrated devices involving numerous advanced radio-frequency (RF) and high-speed digital integrated circuits (ICs) to achieve more capabilities. For effective electromagnetic shielding, a highly conductive transparent film is needed to be developed. In conventional shielding, metals and magnetic sheets have been used as shielding materials. However, since they are normally fragile in bending and opaque, a new type of shields with high flexibility and transparency is necessary to develop for efficient EMC shielding in flexible display devices. In our study, we demonstrate electromagnetic shielding properties of highly transparent conducting films with mesh-type micropatterns on the PET substrate. The numerical analysis through a coaxial air line for the micropatterned conducting films is performed to evaluate the effect of various parameters such as wire width, opening size, and conductivity on shielding effectiveness in ranging from 1 to 6 GHz using HFSS. |
