In this paper one coplanar wide band bandpass filter (BPF) is designed with end-coupled λ/4 open-stub resonator. This coplanar waveguide (CPW) BPF is designed for passband centre frequency 2.5GHz and 100% fractional bandwidth (FBW) at -3dB. The proposed structure exhibits negligible passband insertion loss, sharp transition from passband to stopband, wide attenuation bandwidth, simple fabrication with reduced size and slow-wave characteristics. Thus, these good properties, wide band, smaller size filters are too much applicable in our modern microwave and millimetre wave communication systems.
