Microstrip filter with defected ground structure: a close perspective

  • Arjun Kumar (a1) and Kartikeyan V. Machavaram (a1)

Abstract

This paper presents a close but a beginner's perspective and a comprehensive review of microstrip filters with defected ground structure (DGS). The concept of DGS is inspired by photonic/electromagnetic bandgap structures (EBG/PBG) and metamaterials that are employed in microwave components to achieve a variety of performance enhancement features. Modeling of DGS and metamaterials as an L-C equivalent lumped circuit is much simpler in comparison with complex EBGs/PBGs. In this review, we have given a detailed account of the microstrip filters using DGS.
