Materials & Processes for Printed Antennas

Printed antennas now deliver reliable low to mid frequency performance using high conductivity silver inks, which offer precise features and scalable processing. Emerging silver plated copper (SPC) inks provide a lower cost option with similar RF behavior. At higher frequencies, Henkel’s silver filled inks achieve low roughness and uniform thickness needed for efficient RF designs. Pad printing further enables additive, high throughput manufacturing of 3D antenna structures. Key results and examples will be presented.
