2005 (English)In: JZUS-A - Journal of Zhejiang University. Science, ISSN 1009-3095, Vol. 6 A, no 6, 483-486 p.Article in journal (Refereed) Published
A tunable dual-broad-band branch-line coupler (BLC) utilizing 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 passband is more than 16% of the central frequency.
