monopole
In physics, this term describes a theoretical entity that breaks the symmetry of standard magnetism. While most magnets are dipoles with both a north and south pole, a monopole would exist as a solitary charge. This concept is primarily used in high-energy physics and cosmology to explain the early universe.
In electrical engineering, the term refers to a specific antenna geometry. It is characterized by a single radiating element, which relies on a ground plane to create an "image" of the antenna, effectively simulating a dipole. This makes it a common choice for vehicle-mounted or handheld radio systems due to its compact size.
Meanings
A hypothetical particle or object that possesses only one magnetic pole, either north or south, rather than the standard dipole structure.
Physicists have spent decades searching for a magnetic monopole in cosmic rays.
An antenna consisting of a single straight conductor, typically mounted vertically over a conductive ground plane.
The radio station installed a high-gain monopole antenna to improve its signal reach.
