High Quality Content by WIKIPEDIA articles! A dipole antenna is a radio antenna that can be made of a simple wire. Usually a dipole center-fed (current coupled), but it can also be fed at the end (voltage coupled). It consists of two metal conductors of rod or wire, 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. As of today the dipole antenna is probably the most common antenna type.
