A Compact Defected Ground Microstrip Device with Photonic Bandgap Effects
Filters and other devices using photonic bandgap (PBG) theory are typically implemented in microstrip lines by etching periodic holes on the ground plane of the microstrip. The period of such several holes corresponds to nearly half the guided wavelength of the transmission line. In this paper we study the effects of miniaturization of the PBG device by meandering the microstrip line about one ...

متن کاملCross Dumbbell Periodic Defected Ground Structure Characteristics
The defected ground structure (DGS) is one such technique which were 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. Tthe time of Practical verification, the surface and leaky waves are affected by the propagation errors ...
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...
متن کاملCharacteristics of Guided-wave Electromagnetic Bandgap Structure
1. Abstract The performances of the periodic surface structures (PSS) of different geometric shapes on the ground plane are studied. Simulated results with full wave electromagnetic analyses are in good agreement with those experimental data. The optimal structure of PSS bringing about the perturbation electromagnetic waves and power loss will be determined. The proposed wideband PBG microstrip...
