The filter is consisting of two symmetrical multiple-mode resonators (MMRs) connected to quarter-wavelength interdigital lines. This filter provides, in the passband, an insertion loss of 0.19 dB and a return loss greater than 22.6 dB. Furthermore, the filter occupies an area of 11.54 × 3.11 mm 2 . In this filter design, besides obtaining a uniform in-band transmission response, a notch band centered roughly 5.2 GHz is created by modifying one of two arms in the coupled-line sections. The simulation results are in satisfactory agreement with the measurement ones reported elsewhere. The proposed UWB-BPF presents good performance in terms of insertion loss, return loss, fractional bandwidth and compact size than those reported in the literatureenBand-notchedBandpass filter (BPF)Multiple-mode resonator (MMR)Article
