Abstract:In this letter, we propose a new design of a dual band electromagnetic band gap (EBG) resonator structure feeding a reflector antenna for space multibeam applications. The EBG antenna is composed of a double-layer frequency selective surfaces (FSS) arranged in the longitudinal direction and a square horn as feed. First we devise a technique to adapt the dual band EBG antenna characteristics for this space application which requires the same EBG phase center and the same radiation patterns for the two frequency… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
