Single Walled Carbon Nanotube fibers have been found to be configurable as Antennas that are about 20 times lighter than Copper Antennas while having a better performance at higher frequencies.
A group of researchers from NIST, Rice University reported their work in Applied Physics Letters
This work fills the gap between theoretical and practical demonstrations. The availability of light weight antennas opens up a world of opportunities in various sectors such as Aerospace, wearables, sports wear etc.
The antennas provide an order of magnitude improvement in performance when compared to copper antennas of similar dimensions. Unlike metals these antennae show improved performance at higher frequencies. This would make them ideal for present and future high frequency Wireless communications such as 5G.
