  Publikacja

  • Z. Shaterian
  • M. Mrozowski

  - IEEE Access - Rok 2023

  This paper presents the design and realization of a multifunctional bandpassfilter/displacement-sensor using an edge-coupled microstrip bandpass filter loaded by a pair of split ring resonators (SRRs). It is shown that while the structure acts as a bandpass filter at its operating frequency, the phase of the reflection coefficient from a movable loading resonator at the resonance frequency of the resonator can be used for displacement...

• Dual-Polarized Wideband Bandpass Metasurface-Based Filter

  Publikacja

  • A. Noor
  • S. Kozieł

  - IEEE Antennas and Wireless Propagation Letters - Rok 2024

  This paper presents a novel metasurface-based bandpass filter. The structure is realized by simply patterning a double-sided AD250 substrate, and does not require any vias or insertion of lumped elements. The top layer is an annular- aperture-array with multiple inner conductors, whereas the bottom layer is a first-order Hilbert-curve array. FEM-based simulation results of the filter are obtained using HFSS. The experimental validation...

• Generalized Chebyshev Bandpass Filters With Frequency-Dependent Couplings Based on Stubs

  Publikacja

  • Ł. Szydłowski
  • N. Leszczynska
  • M. Mrozowski

  - IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES - Rok 2013

  This paper presents an accurate synthesis method for inline and cross-coupled generalized Chebyshev bandpass filters with frequency-dependent couplings implemented via open and short stubs. The technique involves the synthesis of a lumped-element prototy pe in the form of a coupling matrix with a frequency-dependent term and the conversion of this prototype to a distributed-element mode l composed of sections of TEM lines. This...

• A Novel Synthesis Technique for Microwave Bandpass Filters with Frequency-Dependent Couplings

  Publikacja

  • N. Leszczynska
  • Ł. Szydłowski
  • M. Mrozowski

  - Progress in Electromagnetics Research-PIER - Rok 2013

  This paper presents a novel synthesis technique for microwave bandpass filters with frequency-dependent couplings. The proposed method is based on the systematic extraction of a dispersive coupling coefficient using an optimization technique based on the zeros and poles of scattering parameters representing two coupled resonators.The application of this method of synthesis is illustrated using two examples involving four and five-pole...

• A Substrate Integrated Waveguide (SIW) Bandpass Filter in A Box Configuration With Frequency-Dependent Coupling

  Publikacja

  • Ł. Szydłowski
  • N. Leszczynska
  • A. Lamęcki
  • M. Mrozowski

  - IEEE MICROWAVE AND WIRELESS COMPONENTS LETTERS - Rok 2012

  This letter presents the design of a microwave bandpass filter with frequency-dependent coupling implemented in substrate integrated waveguide (SIW) technology. The proposed filter implements a four-pole generalized Chebyshev filtering function with two transmission zeros. Resonators are arranged in an extended box configuration with dispersive coupling on a main signal path, which produces an extra zero in comparison to classical...

• A Systematic Search for New Coupling Schemes of Cross-Coupled Resonator Bandpass Filters

  Publikacja

  • A. Lamęcki

  - RADIOENGINEERING - Rok 2014

  In this paper, a systematic approach to an extensive search for topologies of cross-coupled filters with generalized Chebyshev response is presented. The technique applies graph theory to find unique, nonisomorphic filter configurations, and tests whether a specific frequency response can be realized in a given set of topologies. The results of the search are then stored in a database of possible filter configurations.

• Broad Stopband, Low-Loss, and Ultra-Compact Dual-Mode Bandpass Filter Based on HMSIRC

  Publikacja

  • R. Barik
  • S. Kozieł
  • A. Pietrenko-Dąbrowska

  - Electronics - Rok 2023

  In this investigation, an ultra-compact dual-mode bandpass filter (BPF) with a wide stopband re-sponse is realized by using a half-mode substrate-integrated rectangular cavity (HMSIRC). The HMSIRC resonator is designed with a cavity that is rectangular in shape and has metallic vias along three of the sides. The fourth side is open-ended and contains microstrip feed lines. For the purpose of constructing a magnetic wall, a rectangular...

• Miniaturized Inline Bandpass Filters Based on Triple-Mode Integrated Coaxial-Waveguide Resonators

  Publikacja

  • R. Gómez-García
  • M. Mrozowski

  - IEEE Access - Rok 2023

  This work presents a design technique to implement miniaturized cross-coupled bandpass filters in inline physical configurations based on triple-mode resonators. Triple-mode resonances are obtained by using integrated coaxial-waveguide cavity resonators. They consist of two coaxial conducting posts placed in the sidewalls of a rectangular waveguide cavity. In the proposed triplet, a transmission zero (TZ) can be positioned at any...

• Dimensional Synthesis of Coupled-Resonator Pseudoelliptic Microwave Bandpass Filters with Constant and Dispersive Couplings

  Publikacja

  • Ł. Szydłowski
  • N. Leszczynska
  • M. Mrozowski

  - IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES - Rok 2014

  In this paper, we propose a novel technique for the dimensional synthesis of coupled-resonator pseudoelliptic microwave filters with constant and dispersive couplings. The proposed technique is based on numerical simulations of small structures, involving up to two adjacent resonators, and it accounts for a loading effect from other resonators by replacing them with terminations coupled through appropriately scaled inverters. The...
