In this paper, two square shape defected ground structure (DGS) are used for designing a novel hairpin-line narrow band microstrip band-pass filter and these structures are linked by a path where etching process is applied in the ground plane. The path length of DGS cell is 10.6 mm and the path width is 0.5 mm where the dimensions of square shape defected ground structure is 2 mm. The mid-band frequency of the designed filter is 2.22 GHz which is applicable for the satellite and radar communication for the purpose of S-Band. The bandwidth of proposed filter is 1.99 GHz to 2.45 GHz which is useful for narrowband communication. The proposed filter has minimum insertion loss of 0.2946 dB and maximum return loss of 46.64 dB at mid-band frequency 2.22 GHz. Output characteristics of microstrip filter is judged by using simulation tool IE3D 14.1 EM which is based on method of moments (MOM). The proposed microstrip band pass filter has a coverage area of (34.8 mm× 18.25 mm) 635.1 mm2 for the top layer and (21.85 mm× 14.5 mm) 316.825 mm2 for the ground layer which is more compact as compared to other existing band pass filter designs.
