A NOVEL COUPLED LINE COUPLER WITH DEFECTIVE GROUND STRUCTURE (DGS)

INTERANTIONAL JOURNAL OF SCIENTIFIC RESEARCH IN ENGINEERING AND MANAGEMENT, 2022
This paper examines the development of a 10 dB directionally coupled line coupler with defective ground structure (DGS) using HFSS design tool. The coupler operates in the 4 GHz to 6 GHz frequency range with a high directivity of 46 dB. compared to conventional coupled line coupler and S parameters are calculated.

Design and realization of microstrip filters with new defected ground structure (DGS)

Engineering Science and Technology, an International Journal, 2017
AbstractIn this paper, various microstrip filters, such as bandpass (narrow/wideband) filters, dual band bandpass filter and lowpass filters, are designed with new metal strips loaded defected ground structure (DGS). In this proposed DGS, metal strips are introduced in connecting slot of dumbbell shaped DGS (DB-DGS). This new DGS is an improved version
