"WIRELESS: Metamaterials Meld Multiple Modes onto Single Antenna"

One of the world's first mobile phones to use metamaterials--LG's BL-40--allows multiple radio modes to share a single smart antenna. Invented by Rayspan, now a single antenna can meld today's 3G, GMS, WiFi, Bluetooth and GPS with tomorrow's 4G WiMax and LTE standards. Look for thinner, sleeker mobile phones thanks for metamaterial antennas.


Today's multimode mobile phones and other devices, from netbooks to wireless modems to GPS navigators, require complex multielement antennas that need expensive radio-frequency (RF) switches and complicated matching networks when utilizing different communications bands and protocols. But by harnessing the metamaterials recently made famous for their experimental applications as invisibility cloaks, Rayspan (San Jose, Calif.) can now build a single antenna for all communications signals.
