New Bandstop Filter Using Simple Defected Microstrip Structure

A defected microstrip structure (DMS) has similar properties as a defected ground structure (DGS), but without any leakage through the ground plane. In this article, the stopband performance of a DMS is studied, and new single-band and dual-band bandst...

Currently, the defected ground structure (DGS) 1-4 has been widely employed to improve filter performance and reduce filter size. DGSs show good stopband performance and excellent harmonic suppression in microwave circuits design and especially the periodic DGSs, 4 which extend the stopband greatly. DGS increases the effective capacitance and...
