In this paper, a new topology for the design of a highly compact complementary split-ring resonator (CSRR) based dual planar electromagnetic bandgap (DP-EBG) microstrip low-pass filter with a S-shaped geometry is proposed. With the DP-EBG configuration and the S-shaped geometry of microstrip line (MLIN), the proposed structure achieves a very sharp stopband with high attenuation and high selectivity within a very small circuit area. Its passband ripple level is negligible due to the square patch inserted in the MLIN and CSRR in the ground plane of S-shaped geometry. By introducing complementary split-ring resonator (CSRR), the selectivity and the roll-off of the microwave low-pass filter is highly improved. The proposed structure is very simple and easy to fabricate and is highly compatible with monolithic microwave integrated circuit (MMIC) technology.
Author Keywords: Complementary split-ring resonator (CSRR), Electromagnetic bandgap (EBG), low-pass filter.

Abstract
In this paper, a new topology for the design of a highly compact complementary split-ring resonator (CSRR) based dual planar electromagnetic bandgap (DP-EBG) microstrip low-pass filter with a S-shaped geometry is proposed. With the DP-EBG configuration and the S-shaped geometry of microstrip line (MLIN), the proposed structure achieves a very sharp stopband with high attenuation and high selectivity within a very small circuit area. Its passband ripple level is negligible due to the square patch inserted in the MLIN and CSRR in the ground plane of S-shaped geometry. By introducing complementary split-ring resonator (CSRR), the selectivity and the roll-off of the microwave low-pass filter is highly improved. The proposed structure is very simple and easy to fabricate and is highly compatible with monolithic microwave integrated circuit (MMIC) technology.
Author Keywords: Complementary split-ring resonator (CSRR), Electromagnetic bandgap (EBG), low-pass filter.
