UniSa - IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe experimental validation of an effective near-field – far-field (NF–FF) transformation with plane-polar scanning, particularly suitable for quasi-planar antennas, is provided. Such a technique is based on the nonredundant sampling representations of the electromagnetic fields and uses an oblate ellipsoid to model the antenna. A two-dimensional optimal sampling expansion allows the efficient reconstruction of the voltage data needed by the classical plane-rectangular NF–FF transformation. It is so possible to remarkably lower the number of NF data to be acquired, thus reducing in a significant way the required measurement time. Some experimental results carried out at the UNISA Antenna Characterization La b and assessing the effectiveness of the technique are shown.
