Abstract

Optically transparent microstriplines designed using a conductive micro-metal mesh film (µ-MMF) and a conductive wired-metal mesh (WMM) are presented. The transparent microstriplines are fabricated on a transparent acryl substrate with thickness (h_s) of 1.25 mm, relative permittivity (ɛ_r) of 2.6, and loss tangent (tan δ) of 0.009. The average optical transmittance of µ-MMF and WMM is 62% and 71%, respectively, in the visible band (400–750 nm). The sheet resistance of µ-MMF and WMM is 0.08 and 0.01 Ω/sq, respectively. In addition, two types of copper microstriplines are fabricated for performance comparison. Insertion losses (S₂₁) and return losses (S₁₁) of transparent microstriplines of lengths 1, 3, and 5 cm are measured to be under 2 dB and higher than 15 dB up to 6 GHz, respectively.
