An aerial, also known as an antenna, is a transducer which is intended to broadcast or receive radio waves which are a types of electromagnetic waves.
In simple words, antennas transform radio frequency based electrical currents into electromagnetic waves. An aerial generally works in air as well as outer space, and can even function under water. An aerial basically is a collection of conductors which function by generating a radiated electromagnetic field in reaction to an applied alternating voltage and the connected alternating electric current.
Aerials were initially used in the year 1888 by Heinrich Hertz in an attempt to justify the existence of electromagnetic waves predicted and calculated by the hypothesis of James Clerk Maxwell. Aerials are frequently used in radio communication, television broadcasting, wireless LAN, radar, etc.
