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 ?/4 transformer) � 2015 IEEE.EnglishCapacitorsImpedanceInductorsMicrowave circuitsPower transmission linesShunts (electrical)Transmission line measurementsCapacitorsElectric impedanceElectric inductorsElectric linesElectric power transmissionMagnetic materialsMetamaterialsMicrowave circuitsReconfigurable hardwareTanks (containers)Ultra-wideband (UWB)Wireless telecommunication systemsAnalytical studiesComposite right/left handed transmission linesEquivalent circuit modelImpedance transformersShunts (electrical)Transmission coefficientsTransmission-line measurementsWireless applicationBroadband networksConference Paperhttps://doi.org/10.1109/MetaMaterials.2015.7342448
