Abstract :
A novel directional coupler from composite right/left-handed transmission line and artificial transmission line is presented in this paper. The proposed couplers with 6 dB, 10 dB, and 20 dB coupling coefficients are implemented with printed circuit board. The simulated and measured results are compared and analyzed. Simulated results agree well with measured results. The experimental results show that this coupler works well from 1.3 GHz to 1.8 GHz. Meanwhile, the backward and tight coupling characteristics of the coupler are demonstrated in the operational band. In addition, the coupling coefficients can be adjusted easily with a large dynamic range.
