Abstract:Design procedure of a novel transmission line low-pass filter is presented. The filter has a flexible rejection response for a prescribed cut-off frequency and an in-band ripple factor. It is compact by using a Z-shaped coupled-line section, which is loaded with opencircuited stubs. All of the transmission line elements are identical in electrical length, and the impedances can be calculated by solving certain specific equations according to prescribed in-band specifications. The simulated results show that th… 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.
