Marconi had invented the antenna grounded and loaded with a capacity, and discovered how to launch and receive a “surface wave”, namely a wave tightly connected to the ground and suffering lower attenuation than the wave radiated by a non grounded Hertz oscillator.
Marconi and his early wireless stations were illustrated on dozens of di erent cards sold with packs of cigarettes, and he had at least two brands of cigars named after him.

Marconi believed radio waves were the key to wireless communication and dedicated himself to it. Just 20 years old, he began building his own equipment in his attic, aided by his butler.
Marconi the man and Marconi the inventor are two indi- viduals with the outstanding characteristic of simplicity linking the two into one personality. Simplicity is the key- note of his everyday life and of his scientific triumphs; it is the secret of his wizardry.
This paper remembers the main events of the history of radio, events in which Guglielmo Marconi gave his fundamental contri- bution to the development of the new system of communication.
In electronics and telecommunications, a radio transmitter or just transmitter (often abbreviated as XMTR or TX in technical documents) is an electronic device which produces radio waves with an antenna with the purpose of signal transmission to a radio receiver.
A transmitter is a device that sends information as a signal, and a receiver is a device that picks up that signal and converts it back into usable information.
