摘要：
An ultra-wide stopband lowpass filter (LPF) based on the defected ground structure (DGS) is presented in this paper. The proposed LPF is comprised of a cross-diapason-shaped (CDS) pattern along with two dumbbell-shaped pattern DGS. The substrate material is FR4 with dielectric constant of 4.6 and thickness of 0.8mm. The proposed LPF provides a sharp rejection at 2.4GHz with an ultra-wide stopband of 30dB attenuation up to 10GHz. The etched size can be minimized to be 53.8% less than that of the cascaded configuration. The simulation and measurement results of the CDS-DGS-LPF are provided.
