Benvenuti nell'Anagrafe della Ricerca d'Ateneo

La valutazione delle attività di ricerca che si svolgono nelle università ha assunto un'importanza rilevante sia per l'intero sistema universitario sia all'interno di ogni singolo ateneo. Roma Tre si è quindi dotata di idonei strumenti informativi in grado di supportare al meglio le azioni di monitoraggio e di valutazione delle attività di ricerca svolte nei propri dipartimentied ha realizzato una Anagrafe della Ricerca di Ateneo.

The design of a 1-D planar periodic combline leaky-wave antenna that avoids the open-stopband effects as the beam is scanned through broadside is discussed and verified experimentally. This antenna radiates from nearly resonant stubs, which ensures a small leakage constant and hence a high directivity, and shows a single beam scanning through its n = -1 space harmonic in the X-band frequency range. The open-stopband suppression is obtained by applying a recently proposed matching technique within the unit cell [1] that is experimentally validated here for the first time. Measurements are made of the phase and leakage constants, the S-parameters, and the realized gain patterns. Comparisons are made with numerical values obtained from specialized and commercial software and very good agreement is found in all cases.

Abstract:	The design of a 1-D planar periodic combline leaky-wave antenna that avoids the open-stopband effects as the beam is scanned through broadside is discussed and verified experimentally. This antenna radiates from nearly resonant stubs, which ensures a small leakage constant and hence a high directivity, and shows a single beam scanning through its n = -1 space harmonic in the X-band frequency range. The open-stopband suppression is obtained by applying a recently proposed matching technique within the unit cell [1] that is experimentally validated here for the first time. Measurements are made of the phase and leakage constants, the S-parameters, and the realized gain patterns. Comparisons are made with numerical values obtained from specialized and commercial software and very good agreement is found in all cases.
