The antenna was invented by the Russian scientist Popov.
In 1888, Popov, 29 years old, that famous German physicist Heinrich Hertz discovered electromagnetic wave of news, who once aspired to be extended lamp young scientists to friends said: "with my lifetime energy to install lights and for broad Russia, but lit up the small corner: if I can command the magnetic wave, it can be the whole world over!"
So he buried himself in his studies and launched a shock to the new target.
In 1894, Popov made a radio receiver. The core part of the receiver is improved the coherer, Popov the bell as a display terminal, the bell hammer can the detector in the metal scraps shake loose. Bell with an electromagnetic relay drive, when scrap metal detector to detect electromagnetic waves, relay, a power supply is switched on, the bell rang.
Once, Popov found in the experiment, the receiver detects the distance of the radio suddenly increased a lot more than usual.
"What's going on here?" Popov check to check, has been found out why.
One day, Popov accidentally found a wire on a metal chip detector. He took the lead away, not the bell rang; he threw the distance is reduced to the original so close, the bell rang.
Popov was overjoyed, hurriedly put a head of wires to the coherer, and the other end connected to the detector. After re testing, the results show that the use of the antenna, the signal transmission distance.
Radio antennas come out.
