Abstract EN
A novel triple-mode bandpass filter (BPF) using a dual-mode defected ground structure (DGS) resonator and a microstrip resonator is proposed in this paper.
The dual-mode characteristic is achieved by loading a defected T-shaped stub to a uniform impedance DGS resonator.
A uniform impedance microstrip resonator is designed on the top layer of the DGS resonator and a compact bandpass filter with three resonant modes in the passband can be achieved.
A coupling scheme for the structure is given and the coupling matrix is synthesized.
Based on the structure, a triple-mode BPF with central frequency of 2.57 GHz and equal ripple bandwidth of 15% is designed for the Wireless Local Area Network.
Three transmission zeros are achieved at 1.48 GHz, 2.17 GHz, and 4.18 GHz, respectively, which improve the stopband characteristics of the filter.
The proposed filter is fabricated and measured.
Good agreements between measured results and simulated results verify the proposed structure well.
