New inductor loaded composite right left hand impedance transformer for UWB wireless applications
A compact ultra wide band impedances transformer based on new configuration of composite right/left handed transmission line is presented. The proposed design introduces ultra wide band pass frequencies extended from 2 GHz up to 11 GHz with perfect matching transmission coefficient. However, the whole topology is designed using new loaded inductor configuration of CRLH. This L-CRLH is implemented using loaded inductor to construct shunt tank of gap capacitor and strip inductor, and shunt tank formed using patch capacitor with shorted strip inductor. Furthermore, the paper present analytical study, equivalent circuit model, 3D fall wave simulation and fabrication measurement results. The results shows perfect insertion losses equal 0.2 dB and return losses reach to 19 dB within extended band pass band from 2 GHz up to 11 GHz. Moreover, it introduces very compact size equal 2.7×8.6 mm2 (58% size reduction compared to single frequency λ/4 transformer).
