Method for fabricating a transparent antenna

Abstract:

A transparent antenna is fabricated by printing a pattern of catalytic ink onto a web of substrate in one or more conductive regions, wherein a geometry of the conductive regions defines an antenna pattern. A pattern of non-conductive ink is printed in registration onto the substrate in a fill pattern, wherein the fill pattern is an inverse of the antenna pattern within a defined region of interest. A conductive material is electrolessly plated onto the pattern of catalytic ink by transporting the web of substrate through a reservoir of plating solution to provide a corresponding pattern of conductive material, thereby providing the transparent antenna. An average optical transparency in the conductive regions and non-conductive regions is at least 50%, and the average optical transparency in the conductive regions differs from that of the non-conductive regions by no more than 10%.
