In this article, we propose a microstrip low-pass filter (LPF) comprising of open-circuited stubs on the upper surface and a novel defected ground structure (DGS) on the lower ground plane, and discuss the impacts of some of the DGS parameters on the frequency characteristics. Based on this structure, a compact S-band LPF with sharp-rejection is designed and simulated effectively. A center frequency f 0 of 2.65 GHz is obtained by adjusting the dimensions of the DGS cell, and the simulated 3 dB cutoff frequency f c is 2.53 GHz with a sharpness factor (SF) of 0.955.
