Antenna Technology

dipole antenna is a radio antenna that can be made of a simple wire, with a center-fed
driven element. It consists of two metal conductors of rod or wire, oriented parallel and
collinear with each other (in line with each other), with a small space between them. The
radio frequency voltage is applied to the antenna at the center, between the two
conductors. These antennas are the simplest practical antennas from a theoretical point of
view. They are used alone as antennas, notably in traditional "rabbit ears" television
antennas, and as the driven element in many other types of antennas, such as the Yagi.
Dipole antennas were invented by German physicist Heinrich Hertz around 1886 in his
pioneering experiments with radio waves.
