Branch-Line Couplers Using Defected Ground Structure
IEICE Transactions on Communications, 2005In this letter, a novel design of a branch-line coupler with considerable reduction in its size and suppressed harmonic passband is proposed. By embedding a defected ground structure (DGS) unit cell under a microstrip line, compact branch-line couplers are easily achieved. The electrical length is scaled appropriately according to the slow-wave effect.

Modeling of radiation losses in Defected Ground Structures
2016 IEEE International Conference on Engineering and Technology (ICETECH), 2016Defected Ground Structures are useful in many microwave applications. It suffers with radiation and scattering losses through defect in the ground plane. This paper addresses the origin and model of such losses with various 3D EM simulations. This model will be useful in engineering the EMI and losses due to DGS and other defect based resonators.

Quasi-static modeling of defected ground structure
IEEE Transactions on Microwave Theory and Techniques, 2006A quasi-static equivalent-circuit model of a dumbbell-shaped defected ground structure is developed. The equivalent-circuit model is derived from the equivalent inductance and capacitance developed due to the perturbed return current path on the ground and the narrow gap, respectively. The theory is validated against the commercial full-wave solver CST

Effects of a Lumped Element on Defected Ground Structures
30th European Microwave Conference, 2000, 2000In this paper, effects of a lumped element on a DGS (Defected Ground Structure), which is etched on the metallic ground plane, were investigated. In order to demonstrate effects of a lumped element, which is placed on DGS section, we proposed a DGS with a dumbbell shape and implemented a parallel resonator with the proposed DGS.
