Abstract
In this present work, a coplanar waveguide (CPW) ultra-wideband (UWB) bandpass filter (BPF) is proposed using defected ground structure (DGS) and interdigital capacitor having the exact passband frequency range of (3.1–10.6) GHz, minimum passband insertion loss of 0.14 dB and stopband rejection level below 20 dB from 11.8 to 16 GHz. Lumped equivalent circuit model of CPW UWB BPF is also extracted. Mathematical modelling to calculate values of generated inductances, capacitances and resistance of proposed BPF is indicated. Circuit size is miniaturized to an area of 7 mm × 9.3 mm and BPF is simulated on Fr4 substrate with dielectric constant of 4.4 and thickness of 1.6 mm. The proposed BPF is applicable for Bluetooth and wireless devices.
