Analyzing Uncertainties of Rectangular Periodic Defected Ground Structure Characteristics
The defected ground structure (DGS) is one such technique which where intentionally modified to enhance the performance of the ground plane metal of a microstrip circuit. Importantly, in microwave application, the DGS plays an important role in analyzing the effect of surface and leaky waves. During the time of experimental analysis, the surface and leaky waves are affected by the propagation u...

متن کاملA Novel 1-D Periodic Defected Ground Structure for Planar Circuits
A new one-dimensional (1-D) defected ground unit lattice is proposed in order to improve the effective inductance. Increasing the effective inductance makes it easy to control the cutoff frequency characteristics. The proposed periodic defected ground structure (DGS) provides the excellent cutoff and stopband characteristics. In order to show the improved the effective inductance, three DGS cir...
متن کاملA Review of Defected Ground Structure (DGS) in Microwave Design
Electromagnetic bandgap (EBG) or alternatively called photonic band gap (PBG) structures have been attractive to obtain the function of unwanted frequency rejection and circuit size reduction. Researches on the PBG had been originally carried out in the optical frequency. Recently, there has been an increasing interest in microwave and millimeter wave applications of PBG circuits. This paper pr...
