Antenna is used widely in the telecommunication field, military operations, and other applications. It gets an electromagnetic wave and converts it into electric signals. Some antennas receive electric signals and radiate them as electromagnetic waves. A simple radio antenna is a long straight rod. Many indoor TV antennas take the form of a dipole that is divided into 2 pieces and folded horizontally. Numerous outdoor TV antennas have more than one dipole with a central supporting rod. The different types of antenna designs include parabolic satellite dishes and circular loops of wire.
