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.

The word aerial (which is also known as the word antenna) is defined as a transducer. It is basically designed for the purpose of transmission or reception of airwaves or radio waves. These are the two main types of electromagnetic waves.

A television antenna or aerial converts the electrical currents which are generated by television broadcasters into electromagnetic waves and vice-versa. The word antennae is the plural of the word antenna.

In physical terms, an antenna is basically arranged in the form of a series of conductors which generate a radiating electromagnetic field. This is the response to the alternating voltage which is applied and the alternating electric current which is associated with it. This electromagnetic field induces an alternating current in the antenna as well as a voltage between the terminals of the field.
