Description

An antenna is a transducer designed to transmit or receive electromagnetic waves.

In other words, antennas convert electromagnetic waves into electrical currents and vice versa.

Antennas are used in systems such as radio and television broadcasting, point-to-point radio communication, wireless LAN, radar, and space exploration.

Antennas usually work in air or outer space, but can also be operated under water or even through soil and rock at certain frequencies for short distances.

Physically, an antenna is an arrangement of conductors that generate a radiating electromagnetic field in response to an applied alternating voltage and the associated alternating electric current, or can be placed in an electromagnetic field so that the field will induce an alternating current in the antenna and a voltage between its terminals.

Some antenna devices (parabolic antenna, Horn Antenna) just adapt the free space to another type of antenna.
