Who invented the antenna

He was Italian Guglielmo Marconi (1874-1937) in 1906.

It is a device that serves for the captation or irradiation of radio waves.

It is formed by a set of wires in contact with the ground and suspended the certain height, placed in towers, automobiles or in the high one of the buildings.

The antenna receives and transmits waves electromagnetic. These waves are called hertzian waves and spread in the space without conducting wire necessity.

Thanks to them, the antennas can catch the transmissions of radio, television, telegraph, etc…

The first station of radio used, as antenna, a strained wire.

Later, the devices had been developed until arriving at the complex current devices.

The invention of the antenna helped Marconi in its research until leading to the invention of the telegraph without wires.
