A half-wave dipole, also known as a doublet, or the Hertz antenna, is the most commonly used type of dipole antenna. The length of its conductive elements is approximately half of the maximum wavelength (λ/2, the distance between two consecutive maximum or minimum points) in free space at the frequency of operation.
A true half-wave dipole is one half of the wavelength λ in length, where λ = c / f in free space. · A dipole is omnidirectional in the plane perpendicular to ...
