Cylindrical near field to far field

WebSep 27, 2011 · The direct measurement of the radiation pattern of an antenna is often unreachable. A near-field sampling followed by a near-field/far-field (NF/FF) transformation is therefore substituted. This process is, in most cases, applied to antennas placed in free-space or over a perfect electric conductor. Webfar-field patterns can be produced until a full planar near-field measurement is completed. The near-field spherical measurement system can be used for characterizing antennas …
