Feb 1, 2017 · Slots or defects integrated on the ground plane of microwave planar circuits are referred to as Defected Ground Structure. DGS is adopted as an emerging technique for improving the various parameters of microwave circuits, that is, narrow bandwidth, cross-polarization, low gain, and so forth.

In printed circuit board manufacturing, a defected ground structure (DGS) is a purposefully-created defect on the ground plane of a printed microstrip board. It is typically created in the form of an etched -out pattern on the ground plane.

DGS structure and its position rela-tive to the transmission line. The range of structures—of which Figure 1 is only a small sample—arises from different requirements for bandwidth (Q) and center frequency, as well as practical concerns such as a size/shape that does not overlap other portions of the circuit, or a structure

In this paper, we present three types of DGS units which are triangular2head (TH), rectangular2head (RH) and U2shape (US) and their characteristics are compared each other. Further, these DGS units are employed in the design of low2pass filters (LPF) and band2pass filters (BPF) and the obtained performances of each are examined.

This paper presents the design of an H-shape defected ground structure (DGS). Full EM-wave simulation of the design was carried out by using the Computer Simulation Technology (CST) software. The influence of some DGS design parameters on the resonant frequency was simulated and studied.

Oct 1, 2013 · The DGS geometries reported so far include simple shapes such as rectangular dumbbell, circular dumbbell, spiral, “U”, “V”, “H, cross, concentric rings, etc.

Oct 25, 2010 · This chapter addresses the fundamentals of the DGS from its evolution and modeling to the state-of-the-art applications. The DGS geometries reported so far include simple shapes such as rectangular dumbbell, circular dumbbell, spiral, “U”, “V”, “H, …
