Design of Microwave Microstrip Bandpass Filters Using Defected Ground Structures
Articolul prezintă un studiu asupra unor tipuri de filtre trece-bandă (FTB) de microunde în tehnologie microstrip, cu o fantă de cuplaj practicată în planul de masă. Prezenţa unei fante poate conduce la un cuplaj electric mai strâns, sau la creşterea părţii electrice a cuplajului mixt, între cele două rezonatoare planare învecinate. Această structură cu defect de masă („defected ground structur...
متن کاملMicrowave Bandpass Filters Using Couplings With Defected Ground Structures
In this paper some novel types of microwave bandpass filters using defected ground structures are investigated. In the microstrip technology the use of defected ground structures (DGS) allows designs of filters with tight couplings, without the necessity of using very narrow coupling gaps. In multilayer filters DGS can be used as coupling elements between resonators, allowing very compact filte...
متن کاملUltra-Wideband Bandpass Filter Using Hybrid Microstrip-Defected-Ground Structure
A novel ultra-wideband (UWB) bandpass filter (BPF) with a fractional bandwidth (FBW) of about % 110 is presented using the hybrid microstrip-defected-ground structure (DGS). The proposed filter was designed using a combination of hybrid microstrip-defected-ground structure lowpass filter (LPF) with typical quarter-wavelength short-circuited stubs highpass filter (HPF), followed by an optimizati...
متن کاملCompact Microstrip Spurline Bandstop Filter with Defected Ground Structure (Dgs)
This paper presents a new structure to implement compact narrowband high-rejection microstrip band-stop filter (BSF). This structure is the combination of two traditional BSFs: Spurline filter and BSF using defected ground structure (DGS). Due to inherently compact characteristics of both Spurline and interdigital capacitance (used as DGS), the proposed filter shows a better rejection performan...
متن کاملA Comparative Study of Microstrip Bandstop Filters Loaded With Various Dumbbell-Shaped Defected Ground Structure (DGS)
In this paper, a comparative performance of microstrip filters loaded with various dumbbellshaped defected ground structures (DB-DGS) has been studied in terms of their bandstop characteristics. During this course, a new dumbbell shaped DGS having transmetal slit in the connecting slot of the square head in the ground plane has been proposed. This proposed design provides an improved bandstop r...
