Resumen de Dual-band CRLH branch-line coupler in MIM technology
Christophe Caloz, Hoang V. Nguyen
A dual-band (DB) composite right/left-handed (CRLH) branch-line coupler implemented in metal–insulator–metal technology is presented. A simple and accurate circuit-model design procedure for DB CRLH transmission lines is described and applied to the coupler. A prototype operating at 4.2 and 5.2 GHz is demonstrated in excellent agreement with both circuit and full-wave simulations.
