Planar Microstrip Bandpass Filter with Wide Dual Bands Using Parallel-coupled Lines and Stepped Impedance Resonators
A dual-band bandpass filter with wide and highly attenuated stopbands is designed using parallel coupled microstrip line (PCML) and stepped-impedance-resonators (SIRs). The proposed filter is composed of a pair of highly coupled PCML-SIR structure and a central resonator using a low impedance rectangular microstrip. Initially, the wide dual-band performance is achieved by creating a transmissio...
متن کاملTri - band Microstrip Bandpass Filter Using Dual - Mode Stepped - Impedance Resonator
© 2013 ETRI Journal, Volume 35, Number 2, April 2013 This letter presents a compact dual-mode tri-band bandpass filter by using a short-circuited stub-loaded stepped-impedance resonator (SIR) and a short-circuited stub-loaded uniform impedance resonator. Also, a hairpin SIR geometry is introduced to miniature the size of this filter while maintaining excellent performance. The use of a short-ci...
متن کاملNovel Compact Dual - Band Bandpass Microstrip Filter
In this paper, a novel microstrip structure is developed to realize a dual-band bandpass filter. The proposed bandpass structure uses a microstrip resonator with two independently controlled resonance frequencies producing two frequency bands of interest controlled by adjusting the dimensions of the resonator. Parametric analysis is performed on the structure to determine the optimum dimensions...
متن کاملWideband Tri-band Filter Design using Stepped-impedance Stub Resonators
This letter presents a wideband tri-passband filter in which tri-section stepped-impedance shunt-stubs are used as tri-mode resonators, connected by transmission lines. Developed from the topology of quarter-wavelength stub filters, these filters have much wider passbands compared to many other designs published. The stepped-impedance stubs also contribute transmission zeros between the passban...
متن کاملMicrowave Dual-Band Bandpass Filter using L-shaped Stepped Impedance Resonators
This work demonstrates a microwave dual band bandpass filter using two L–shaped stepped impedance resonators (SIRs) and a coupled feed structure. The coupled feed structure can be a single sided or a double sided structure. Two sets of physical parameters are used to control the coupling coefficient and external quality factor. Thus, the specification, such as the central frequencies and the ba...
