This investigation proposes a novel dual-mode patchbandpass filter (BPF) that uses defect ground structure (DGS) to suppress spurious response. The proposed dual-mode patch BPF has exhibits a wide stopband characteristic owing to that uses the bandgap resonant characteristic of DGS in the harmonic frequency of the dual-mode patch BPF. The novel proposed filter demonstrates the frequency characteristics with center frequency f_0=2.2GHz, 3-dB bandwidth (FBW) of 8% and wider stopband from 2.6 to 6GHz at the level of -35dB. The experimental and simulated results agree.
