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.
EnglishA microstrip-based leaky-wave antenna for two-sided frequency beam scanning and broadside radiation is presented. In particular, the optimized "bull-eye" ring structure is designed to support leakage of the fundamental TM mode of the guiding structure in a regime without any other leaky- or surface-wave modes. Also by following suggested design rules, to achieve good isolation between the printed rings and the TM source, a beam scan angle range of 121 degrees can be realized over an operating bandwidth of more than 40% with antenna mismatch losses of less than 0.14 dB. Supporting numerical calculations are also in agreement with the simulations and antenna measurements.
