Design of Coupled Resonators Bandpass Filter with Defected Ground Structure
In this paper a four-pole elliptic function bandpass filter is designed with two ground slots. A research of microstrip bandpass filters (BPF) using defected ground structures (DGS) is presented. DGS technique allows designs of tight couplings without the necessity of using very narrow coupling gaps. The simulator Sonnet is used to design the resonator and to calculate the coupling coefficient ...
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 کاملDesign and Analysis of Compact UWB Bandpass Filter with Wide Passband Using Defected Ground Structure
A compact ultra-wideband (UWB) bandpass filter (BPF) with wide passband using defected ground structure (DGS) is proposed. The proposed UWB filter is constructed by cascading a high pass filter (HPF) and a lowpass filter (LPF). HPF with short-circuited stubs is used to realize the lower stopband and a LPF is used to attenuate the upper stopband. In order to make the filter size compact, DGS tec...
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 کاملCompact Tunable Dual-band Bandpass Filter Based on Substrate Integrated Waveguide and Defected Ground Structure
A compact tunable dual-band bandpass filter (BPF) based on substrate integrated waveguide (SIW) and defected ground structure (DGS) is investigated in this paper. The second passband can be flexibly controlled by changing the dimensions of the updown DGSs whereas the first passband is fixed. The proposed filter exhibits improved selectivity due to the introduction of four left-right DGSs genera...
