Compact 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...
متن کاملCompact Broadband Dual-band Bandpass Filters Using Slotted Ground Structures
Dual-band bandpass filters featuring compact size and flexible frequency choice are demonstrated using resonators based on slotted ground structures. Two resonators based on slotted ground structures form the basis of the filter design. The resonators allow the back-to-back and face-to-face embedding configuration, hence, greatly reduces the physical size of the filters. By changing the sizes o...
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 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 UWB Band-Pass Filter with Dual Notched Bands Based on Novel Defected Ground Structures
A compact ultra-wide-band (UWB) band-pass filter (BPF) with dual notch bands is presented using novel defected ground structures (DGS). A couple of triangle-ring resonators with four open-stubs fed by a couple of inter-digital coupled structures is developed to meet the UWB requirement of a uniform 3.1GHz to 10.6GHz full-band transmission response. Dual notch bands are generated for filtering o...
