Carbon nanotubes to slim mobile phones: Super-lightweight 'nantennas' shown to work as well as copper

Is there anything that can't be made lighter, stronger and cooler-sounding with carbon nanotubes?

The latest technology to get a nano-makeover is mobile phone antennas - which could lead to lighter, smaller handsets in a matter of years.

Aerials are important because of the sheer number of radios packed into a single phone. Most modern mobiles can work on a range of 2.5G and 3G frequency bands, plus Bluetooth, FM radio and possibly GPS, Wi-Fi, near field communication and even RFID.

Nanotech antenna

The University of Cincinnati has long been known for its world-record-breaking carbon nanotubes. Now researchers there have discovered that spinning carbon nanotubes (CNTs) into longer fibres makes them into excellent nanotech antennas - or 'nantennas'.
