“Nantennas” to Replace Copper Antennas

Due to their light weight, CNAs or Carbon Nano tubes are increasingly been chosen by technical experts to replace weighty materials in their products. Researching about carbon nanotubes is best done at University of Cincinnati; which introduced finest functioning CNAs. Now, researches are heading towards giving the world Nantennas; antennas made up with carbon nanotubes.

University of Cincinnati has recently discovered that carbon nanotubes transform into exceptional nantennas, when twisted into elongated strands. Associate Professor of Physics Mr. David Mast performed a little experiment to prove this hypothesis.

He obtained a 25 micron carbon nanotube fiber, double-sided transparent sticky tape and silver adhesive; and crafted a dipole carbon nanotech antenna. Furthermore, he replaced his original mobile handset antenna with the one he had created himself; the result was remarkable. Without the “nantenna” mobile screen showed no service signals, but provided four to five bars with the newly formed aerial.

Though these light weighed antennas provided excellent service; they were complicated to handle, as they “float on ambient air.” Electrons travel very well in these nanotubes, because of the Skin Effect; they want to move towards the surface area or the Skin of nanotubes. Nanotubes are five times stronger maximum stretching force.

Antennas are important for a mobile phone in order to receive better quality signals and perform well. A mass of different kinds of electromagnetic waves are packed into a single handset, usually, which emphasizes necessity of an aerial. Carbon nantennas can lead to smaller and light weighed cell phones in the future.
