Abstract
The idea of a "phase-centre" for a feed antenna is frequently used when designing a system to be fed by the antenna. The phase-centre is loosely thought of as the point from which the beam emanates but that will be uniquely defined only for a beam which has a truly spherical phase-front and that is rarely the situation with a feed antenna, even in the far-field.
