Abstract :
A CPW (coplanar waveguide) coupled-line directional coupler based on CRLH (composite right/left-handed) cascaded structures is designed, analyzed and then fabricated. The technological realization of the coupler involves one mask process on silicon substrate. The measured frequency bandwidth is from 10.5 GHz up to 13.5 GHz fitting well the simulation results.
