Abstract:In this paper, the design, fabrication, and test of an additive manufactured double-ridged horn antenna optimized to work in ultra-wide-band frequencies is introduced. In particular, to build this antenna, the fused deposition modeling fabrication method is selected. The plastic-made device is then coated by using conductive ink. The double-ridged horn is conceived as a monolithic block. In this way, performance degradations caused by fabrication inaccuracies are minimized. A very good agreement between the si… 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.
