Abstract
Method and equipment are disclosed for picking up the radiation pattern of an antenna to be tested from measurements in near-field. The antenna to be tested is illuminated by a transmit antenna having wavefronts in the shape of circular cylinders. The radiation pattern of the antenna to be tested then is expressed by an integral transform of a unidimensional function which is solved by computing means.
