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.
This paper presents the results in modeling, technological realization and measurements of a coupled-line directional coupler, based on CRLH (Composite Right/Left-Handed) transmission lines. The CRLH transmission lines consists of series connected CPW inter digital capacitors and parallel connected CPW inductors. The studied devices were fabricated on silicon substrate for a subsequent integration...
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, using CPWs (CoPlanar Waveguides). The preliminary measurements were also performed, showing that the experimental results fit well the simulation results.
