The equivalent current approach for computing far-fields from measured near fields is presented. In this technique, the radiating antenna is replaced by equivalent currents which reside on a fictitious surface which encompasses the antenna. The measured near-fields are used to determine the equivalent currents. Accurate far-fields over large elevation and azimuthal ranges can be found from measurements on simple surfaces, such as a plane. Numerical results are presented.
