✦ Synopsis

Abstract

A broadband bandpass filter (BPF) with compact size and high selectivity performances is proposed using the dual‐mode folded‐T‐type resonator and the identical short stub loaded parallel‐coupling feed structure.The resonator can generate one even‐mode and one odd‐mode in the desired band. Two resonant frequencies can be adjusted easily to satisfy the bandwidth of the BPF. The feed structure can generate four transmission zeros near the cutoff frequencies and in the stopband, leading to sharp skirt and deep stopband. One filter prototype with the fractional bandwidth of 58.89% is fabricated for experimental verification of the predicted results. The size for the resonator is only 0.156λ~g~ × 0.303λ~g~ in which λ~g~ is the guided wavelength of 50 Ω microstrip line at the center frequency. © 2011 Wiley Periodicals, Inc.
