A W-shaped microshield coupled parallel coplanar waveguide (CP CPW), which is a new type of CP CPW, is proposed. Closed-form expressions are presented for calculating the quasistatic parameters of this coupled structure by using conformal mapping techniques. The effect of the W-shaped conductor backing on the coupling between CPWs is also discussed. Comparisons are made between the present numerical results and the results available in the microwave literature for CPW V-shaped microshield coupled lines (CWVMCLs) and CP CPWs with a flat conductor backing. In addition, the coupling coefficient of the coupled CPWs is shown to be significantly lower than that of the CWVMCLs in the literature.
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.
