Summary:Defected Ground Structures (DGS) have been utilized to manipulate the ground currents to achieve various electromagnetic properties including miniaturization, filtration and increase in directivity. This paper presents the application of Split Ring Resonator (SRR) as DGS on a three way power divider which alters the divider properties to match slow wave structures, thereby achieving reduction in size. Through placement of defects at two optimized locations, in contrast to conventional techniques of loaded lines and repetitive structures, the miniaturized divider attains similar results as the primary divider. In comparison to the original dimensions of 30.5 × 26.8 mm 2 , the miniaturized version measures 26.5 × 20.8 mm 2 resulting in a collective area reduction of 32.6%.
