چکیده
This paper describes a method for designing tunable coaxial bandpass filters based on an inserted stepped impedance resonator (SIR). The miniaturization of the is realized by shape structure. In addition, extended tuning range can be achieved utilizing SIR. A third-order filter with constant absolute bandwidth designed and fabricated verification. exhibits wide from 2.13 GHz to 3.54 (52.4%), over which (ABW) varies within 97.5 ± 5.5 MHz (±5.6%).

Compact Dual-Band Bandpass Filter Based on Quarter Wavelength Stepped Impedance Resonators
This paper presents a compact dual-band bandpass filter that involves using the quarter wavelength stepped impedance resonators (SIRs) for achieving simultaneously compact circuit size and good dual-band performance. The filter is designed at 2.4 / 3.5 GHz and constructed by two pairs of quarter wavelength SIRs and source-load lines. By properly tuning the impedance ratio, length ratio and radi...
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 کاملDesign of Compact Quadruplexer Based on Defected Stepped Impedance Resonators
A novel compact quadruplexer based on defected stepped impedance resonator (DSIR) with high isolation is presented in this paper. The proposed quadruplexer consists of a common input feeding line, four kinds of folded DSIRs and four individual output feeding lines. Considering the loading effect among channel filters, the input DSIRs must be properly located with respect to the common feeding l...
متن کاملMiniaturised microstrip bandpass filter using stepped impedance ring resonators - Electronics Letters
Introduction: Emerging indoor geolocation systems use either geometric techniques [1, 2], or pattern recognition algorithms [3, 4] to locate a user. This is done in two stages. The first stage is to observe some characteristic of the transmitted signal, such as received signal strength (RSS), or delay (TOA) to derive location metrics. The second stage is to feed these metrics into a geolocation...
