Tree-Shaped Antenna for Wireless and 3G Connections
Engineers at the American University of Beirut have developed an antenna modeled after the national icon - Lebanon's cedar tree - that can be used for wireless and 3G connections. The team found that the geometry of the cedar, based on repetitive triangular parts, allows a similarly shaped antenna to operate at multiple frequencies, which makes it suitable for many types of wireless devices such as mobile phones. The antenna is made from copper and cost six dollars to make, but it would be reduced to just a few cents once it is mass produced.
