Monopole may refer to:
*
Magnetic monopole
In particle physics, a magnetic monopole is a hypothetical elementary particle that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). A magnetic monopole would have a net north or south "magneti ...
, or Dirac monopole, a hypothetical particle that may be loosely described as a magnet with only one pole

Monopole (mathematics)
In mathematics, a monopole is a connection over a principal bundle ''G'' with a section of the associated adjoint bundle.
Physical interpretation
Physically, the section can be interpreted as a ''Higgs field'', where the connection and Higgs fie ...
, a connection over a principal bundle G with a section (the Higgs field) of the associated adjoint bundle

multipole expansion
A multipole expansion is a mathematical series representing a function that depends on angles—usually the two angles used in the spherical coordinate system (the polar and azimuthal angles) for three-dimensional Euclidean space, \R^3. Similarly ...

Monopole (wine) A ''monopole'' (French language, French for 'monopoly') is an area controlled by a single winery (wine company) and can be as small as a named vineyard (''lieu-dit'') or as large as an entire'' appellation d'origine contrôlée'' (AOC). Frequently t ...
, an appellation owned by only one winery

Monopole antenna
A monopole antenna is a class of radio antenna consisting of a straight rod-shaped conductor, often mounted perpendicularly over some type of conductive surface, called a ground plane.
The driving signal from the transmitter is applied, or ...

Dyon
In physics, a dyon is a hypothetical particle in 4-dimensional theories with both electric and magnetic charges. A dyon with a zero electric charge is usually referred to as a magnetic monopole. Many grand unified theories predict the existence of ...
