Compact and Broadband Coplanar Waveguide Left-Handed Metamaterial Transmission Line for RF/ MICC Application

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 mm
²
. 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 be well incorporated with RF/MMIC applications
