Antennas that use recieve and transmit radio waves are made of metal conductors like aluminium and copper. However these metals cannot be used to make ultrathin antennas, which are used in the modern wearable communications system. Researchers have developed possibly the thinest radio frequency antenna which is 1/100th the size of human air. They developed the antenna by spraying layers of niobium atoms onto a plastic substrate. The antenna is flexible and capable of propagating radio frequency waves in all directions . It can be tuned from 2.01 to 2.80 GHz, which includes the frequency required by Bluetooth and Wi-Fi
