Compact 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...
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 کاملDesign 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 کاملDesign and Simulation of Microstrip Hairpin Bandpass Filter with Open Stub and Defected Ground Structure (DGS) at X-Band Frequency
In this paper we have designed and simulated a Band Pass Filter (BPF) at X-band frequency. This filter is designed for X-band weather radar application with 9500 MHz center frequency and bandwidth -3 dB is 120 MHz. The filter design was performed using a hairpin microstrip combined with an open stub and defected ground structure (DGS). The substrate used is Rogers RT5880 with a dielectric const...
