Abstract :
A new coplanar-waveguide coupled structure is proposed by incorporating a backed conductor on the other side of the substrate. For this new coupled structure, the effective dielectric constants as well as the characteristic impedances of the odd and even modes are calculated by the spectral-domain method. In this study, the proposed coupled structure is characterized by carefully examining the related coupling coefficient and the associated field distributions
