Abstract

Application of metamaterial left-handed transmission lines to design 180deg power dividers is considered. Design of microstrip and coplanar miniaturized rat-race rings based on artificial left-handed and right-handed transmission line sections is presented. The devices have been implemented as quasi-lumped-element multilayer structures on low-temperature co-fired ceramics. Novel broadband Wilkinson-type 180deg power dividers using metamaterial left-handed transmission lines are proposed.
