A wideband substrate integrated waveguide (SIW) power divider with enhanced out-of-band rejection is proposed. Periodic butterfly radial slots are etched on top layer of SIW to realise a pass-band combining with high-pass characteristics of SIW. An experimental circuit has been fabricated by the standard printed circuit board process. Simulated results are compared with measured data and good agreement is reported.
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.
