Abstract

This paper is devoted to the experimental validation of two direct near-field-far-field transformations with cylindrical scanning for elongated antennas requiring a minimum number of near-field measurements. They rely on the nonredundant sampling representations of electromagnetic fields and employ two different source modellings suitable to deal with electrically long antennas. These transformations allow the accurate reconstruction of the antenna far-field pattern in any cut plane directly from the collected near-field data without interpolating them. Their effectiveness is assessed by the good agreement between the so recovered far-field patterns and those obtained by means of the classical near-field-far-field transformation with cylindrical scanning.
