Definition: the location of a point associated with an antenna, if it exists, such that, when it is taken as the centre of a sphere or a circle, the phase of a given field component in the far-field region remains essentially constant at least over that portion of the surface of the sphere or over an arc of the circle where the radiation is significant

NOTE – Some antennas have different phase centres dependent on the plane containing the circle being considered.
