In radio and telecommunications, a dipole antenna or doublet is one of the two simplest and most widely used types of antenna; the other is the monopole. The dipole is any one of a class of antennas p

…varieties of "linear" dipoles, the two arms or "poles" can be bent into a "V" shape, even though each individually may be a mostly straight line. The dipole consists of two conductors, usually metal rods or wires, usually arranged symmetrically, end-to-end, with one side of the balanced feedline from the…

Cage dipole antennas in the Ukrainian UTR-2 radio telescope. The 8 meters (30 feet) long by 1.8 meters (6 feet) diameter galvanized steel wire dipoles have an operating frequency range of 8–33 MHz.
Length reduction factor for a half-wave dipole to achieve electrical resonance (purely resistive feedpoint impedance). Calculated using the induced EM
Length reduction factor for a half-wave dipole to achieve electrical resonance (purely resistive feedpoint impedance). Calculated using the induced EMF method, an approximation that breaks down at larger conductor diameters (dashed portion of graph).
