Antennas are the electronic devices that are used for reception and transmission of radio waves. In other words it is an arrangement of aerial electronic conductors that are designed to receive and transmission of radio waves. Antennas convert radio frequency electric currents into electromagnetic waves. Antennas are used in all most all the electronic devices. They are used to broadcasting, and telecommunication purpose. Mainly the antennas work in the open space. For short distances the antennas are made to work under water, through soil, and rock. Antennas generate an electromagnetic field. Many types of antennas are available for different electronic devices.

Antenna reception:

An antenna is a simple and effective device. Antennas are used for reception of electromagnetic waves. The electric field of an electromagnetic wave induces a small voltage. It is induced in each segment of the electric conductors. The induced voltage depends on the length of the conductor and its electrical field. The voltage of the conductor depends on the relative orientation of the segment and the electrical field. Each small voltage induces a current. This current circulates through a small part of the antenna impedance. The voltage of the antenna depends on the relative orientation of the segment and the electrical field. Normally antenna reception depends on the height of the antenna.

Applications of an antenna:

There are many types of antennas that are used in our day-to-day life. They have become one of the most important thing or devices to get a proper enjoyment. Antennas are used in a wide range. Antennas are used at home and they have their application in almost all the fields of technology. For the reception of wideband scanners have outdoor antenna system. Antennas are used for reception of multiple satellite signals. The TV and radio systems have antennas for proper and clear signals. The antennas used in the radars also. These detect the foreign signals. Antennas are used in mobile communication systems. They are also used in telecommunication systems. FM antennas work best when they are sized for the wavelength of a particular frequency. Antennas are used for panel measurements, surface measurements, deformation measurements and many other fields.
