A novel realisable dual composite right/left-handed (D-CRLH) coplanar waveguide (CPW) transmission line (TL) in GaAs MMIC technology demonstrated by theoretical analysis and experimental results is presented. A D-CRLH TL is the dual of the conventional CRLH TL in the sense that it consists of series LC parallel tanks and shunt LC series tanks. However, an ideal D-CRLH TL cannot be realised because...
A GaAs MMIC technology of the novel compact left-handed bandpass filter consisting of one left-handed (LH) transmission line (TL) and one dual composite right/left- handed (D-CRLH) TL is presented. The D-CRLH is the dual of the conventional CRLH in the sense that it consists of a LC parallel-tank impedance and of a LC series-tank admittance. In contrast to the conventional CRLH TL which has LH operation...
A GaAs solid state passive coplanar waveguide (CPW) left-handed metamaterial medium is proposed and validated by measured results. The unit cell of the fabricated structures has a size of 0.09 mm2. The left handedness range of the solid state left-handed structure extends from 2.3 GHz to 17.5 GHz. The compactness and broad left-handed operating bandwidth make the presented left-handed metamaterial...
A fully integrated coplanar waveguide (CPW) left-handed (LH) metamaterials medium for RF/MMIC applications is proposed and demonstrated by measurements. LH metamaterials have the potential to miniaturise RF/MMIC circuits and in this paper, we present a novel, fully integrated LH transmission line (TL). The compactness of the proposed LH-TL is the key advantage in integrated RF/MMIC circuit applications.
