Metamaterials can do all sorts of cool things in theory, like create invisibility cloaks or focus lasers. In practice, though, they're rather less useful. Or at least they were, before the team at Fractal Antenna figured out that a simple sleeve made out of fractal-based metamaterials triples the bandwidth of a simple monopole antenna and boosts its gain by 3dB. All you need to do is slip the fractal sleeve on and, hey presto, instant super antenna. You can see it demonstrated in the video after the break before reading all the nitty, gritty, infinitely-repeating details in the PR, which is down there too.Scientists finally find a practical use for metamaterials: boosting antenna performance (video) originally appeared on Engadget on Wed, 24 Nov 2010 04:29:00 EDT.
