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.
EnglishWe present the design and analysis of a K-band radially-periodic leaky-wave antenna radiating a circularly polarized broadside pencil beam. The structure is constituted by a metallic strip grating printed on top of a single-layer grounded dielectric slab, and is fed on the bottom by means of a square array of printed surface-wave launchers. The structure is optimized to support the fast n = -1 spatial harmonic, whose behavior has been accurately characterized through a full-wave dispersive analysis developed by means of an in-house method-of-moments (MoM) code. By proper phasing the four independent feeding points, linear or circularly polarized pencil beams can be obtained by exciting a dominant but weakly-attenuated, cylindrical TM leaky-wave mode. In this way, highly-directional broadside pencil beams showing good polarization purity can be obtained. The proposed design is of interest for modern satellite and terrestrial point-to-point communications.
