Abstract: A tunable dual-broad-band branch-line coupler (BLC) utilizing left-handed (CRLH)%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>composite right/left-handed (CRLH) transmission lines is presented. Two λ/4 segments consisting of CRLH transmission lines are added to each port to broaden the dual bands of the branch-line coupler. Numerical simulation and optimal design of the novel coupler are presented. The dual bands of the novel coupler are tunable and broad. The 1-dB bandwidth of each pass band is more than 16% of the central frequency.

maybe it is a good design.
