Abstract :
Using a combination of right-handed and left-handed transmission lines to design of miniaturized directional couplers (DC) is considered. Design of miniaturized 3-dB and 10-dB quadrature DC and a rat-race hybrid for wireless applications is presented. Design of a dual-band 3-dB DC is reported as well. All the DCs have been designed as fully-integrated multilayer LTCC structures containing no SMD components.
