Abstract
A method of increasing conductivity in ink using radio frequency energy. A conductive ink comprising a plurality of conductive particles and a binder is printable on a surface, such as a RF antenna. A RF source is used to apply a RF signal to the conductive ink to decrease electrical resistance in the conductive particles via coherence. Once the conductive particles are sufficiently cohered in a state of lower resistance, the binder is cured to maintain the state of lower electrical resistance and improved conductivity of the conductive ink.
