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.
EnglishAn effective technique is proposed in this paper for evaluating the directivity of an antenna under test from near-field measurements on a cylinder. It employs a closed-form formula for computing the total radiated power from the knowledge of the radiation intensity samples on the far-field sphere. These samples are determined via a probe-compensated near-field–far-field transformation and result to be even in number on each parallel. The effectiveness of such a procedure is assessed through numerical tests.
