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.
EnglishIn this paper, we present the design of an Electromagnetic Band-Gap (EBG) leaky-wave antenna consisting of a two-dimensional lattice of dielectric cylinders above a ground plane. The radiation from an electric line source embedded in the EBG open waveguide is modeled by means of suitably excited leaky modes. An in-depth dispersive analysis has showed how a multiplicity of modes, both guided and leaky, propagates within the structure. However, by properly placing an elementary source within the lattice, a single leaky mode of the EBG structure has shown to provide a highly convergent representation of the radiated far field. Based on the knowledge of the leaky-mode attenuation constant, it is possible to truncate the structure longitudinally in order to obtain a radiation efficiency of 96 %. This study led to the design of an antenna operating at a frequency belonging to the 5G millimeter-wave bands. Excellent agreements have been obtained between the theoretical results based on leaky-wave radiation and ad-hoc and full-wave commercial simulators.
