Abstract:This research proposes a miniaturized antenna with a novel design for the ultra‐wideband (UWB) multiple‐input multiple‐output (MIMO) system. The UWB‐MIMO tree‐antenna (UMTA) design consists of two symmetrical designs with minimum inter‐element spacing of 53 mm on the same negative Taconic substrate. Three UMTA geometrical orientations, i.e., MIMO (0 °‐R), MIMO (180°‐R), and MIMO (0°‐U), were analyzed in terms of the reflection coefficient (< −10 dB), mutual coupling, and correlation coefficient. The UMTA is suc… 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.
