Compact Design Method for Planar Antennas with Defected Ground Structures
Electronics (Switzerland), 2023 In this paper, a compact antenna design method is proposed for microstrip patch antennas using a double-layered defected ground structure (DGS) configuration. While a conventional single-layered defected ground structure yields a lower resonant frequency

The Use of Defected Ground Structures in Designing Microstrip Filters with Enhanced Performance Characteristics [PDF]
Procedia Technology, 2014 Until recently, microstrip filter designs were being done with full metallic ground-plane present on one side of the substrate. The state-of-the-art, however, changed when deliberately created defects in the ground (called Defected Ground Structures or ...

Defected and floating ground structures for vertical interconnects
2009 European Microwave Conference (EuMC), 2009 Defected and floating ground structures for vertical interconnects are investigated up to the E-band. For quasi symmetrical microstrip-to-microstrip (MS-to-MS) transitions the effect of shape and size of ground plane cutouts is studied. In addition, floating ground pads are proposed to enhance the matching of asymmetrical microstrip-to-stripline (MS-to-

A Reconfigurable Filter Using Defected Ground Structure for Wideband Common-Mode Suppression
IEEE Access, 2019 A wideband common-mode (CM) suppression reconfigurable filter is proposed for high-speed all-pass differential circuits. The filter adopts three varactor-loaded compact defected ground structures (DGSs) to achieve continuous reconfigurability in its ...

Comparison of Planar Fractal Filters on Defected Ground Substrate
Radioengineering, 2012 The paper discusses approaches to the reduction of dimensions of planar filters (microstrip ones and coplanar ones). Filter dimensions are reduced by applying the fractal theory to the geometry of a filter, and by the defecting of the ground plane of a ...

A general circuit model for defected ground structures in planar transmission lines
IEEE Microwave and Wireless Components Letters, 2005 This paper presents a general circuit model for planar transmission line defected ground structures (DGS) that exhibits multi electromagnetic band gaps or stop bands in frequency responses. The proposed equivalent circuit consists of lumped elements that
