An additive manufacturing process is described that produces transparent antennas (> 80%T) on flexible substrates. The low cost, roll-to-roll process allows for unprecedented conductivity (<0.5 ohms/square) of the transparent conductors, which consist of copper microwires. The microwires are passivated for corrosion prevention, the reflectance is eliminated, and the color made neutral. Additional inline processes are employed to enhance the ability to hide antennas in windows and on surfaces in ways that complement the transparency of electrodes. A variety of applications that can benefit from the technology (automotive, wearables, IOT, cellular, energy harvesting, and military) will be discussed along with the capabilities of the process.
