Transparent Antenna Using Metal Mesh Fabricated by Electric-Field-Driven Microscale 3D Printing

This paper presents a new method for fabricating transparent antennas using metal mesh. A transparent microstrip antenna for application at 2.45 GHz is fabricated on a glass using electric-field-driven (EFD) microscale 3D printing combined with a micro-plating process, obtaining a sheet resistance of less than 0.4 Ω/sq and 78% transparency, which also achieves good impedance matching and good agreement between simulation and measurement. Compared to traditional methods such as photolithography and laser writing, it reduces manufacturing costs and enhances the conductivity of low-temperature-cured silver paste materials. Additionally, it also enables customization, providing a cost-effective and efficient solution for the production of transparent metal mesh antennas.
