Rice University researchers found that carbon nanotubes configured configured as wireless antennas can be as good as copper antennas but 20 times lighter. This technology should come in handy for the aerospace, wearables, and health/medical industries. One key property they discovered is carbon nanotubes are easier to handle than copper antennas at thin gauges. Furthermore, I find it very interesting that carbon nanotubes appear to have far reaching uses and we've barely scratched the surface so far. Read the full text of the paper here.
Contrary to earlier results by other labs (which used different carbon nanotube fiber sources), the Rice researchers found the fiber antennas matched copper for radiation efficiency at the same frequencies and diameters. Their results support theories that predicted the performance of nanotube antennas would scale with the density and conductivity of the fiber.
