## Abstract A method to obtain a main plane farβfield radiation pattern of an antenna under test (AUT) from the correspondent main plane nearβfield pattern in a circular scanning is presented. The method is based on the reconstruction of a set of magnetic equivalent currents radiating in free space
## Abstract When the field radiated by an antenna is measured in the nearβfield region, this must be transformed into farβfield. If a spherical wave expansion is used for this transformation, the transmission formula must be solved, and hence the probe receiving coefficients must be known. Normally
