Researchers at the University of Illinois have come up with a nanoscale printing technique that allows for the creation of so-called 3D antennas. The researchers printing process uses nanoparticle silver ink onto a curved substrate, as shown up above. The resulting components "exhibit performance metrics that are an order of magnitude better than those realized by monopole antenna designs." In fact these creations are said to approach the Chu-Harrington Limit of theoretical performance in an antenna. Plus, they look really cool...too bad they will hidden away inside your mobile device.
