Dielectric resonator bandstop filters [PDF]

open access: yes, 2011
Dielectric resonators have been widely employed in wireless and satellite communication systems due to their inherently large Q allowing them to fashion low loss and narrow bandwidth filters.

Micromachined microwave filters [PDF]

open access: yes, 2003
Microwave circuits in the millimetre wave region demand low loss, and low dispersion transmission lines. The work carried out in this thesis is on low loss transmission lines and filters, based on a square coaxial transmission line which is made only of ...

Design of superconducting ultra‐wideband filter with wide stopband based on quintuple‐mode resonator

open access: yesElectronics Letters, 2023
In this paper, a new ultra‐wideband (UWB) bandpass filter (BPF) based on QMR (quintuple‐mode resonator) loaded with quasi‐lumped elements is proposed for wide stopband application. The method of connecting five folded U‐shaped resonators with rectangular

Tunable microwave filters using ferroelectric thin films [PDF]

open access: yes, 2009
Frequency agile microwave devices based on Barium Strontium Titanate (BST) thin films have gained a lot of interest in recent years. The frequency agility of the ferroelectric devices is based on the external DC electric field controlled permittivity of ...

Single‐ and triple‐band bandpass filters using novel perturbed isosceles right‐angled triangular SIW cavities

open access: yesIET Microwaves, Antennas & Propagation, 2021
Herein, a rigorous derivation of an isosceles right‐angled triangular (IRT) metallic cavity is analysed. Then, the transverse field components in the IRT substrate‐integrated waveguide (SIW) cavity are derived, and the expression of the resonant ...

Distortion mechanisms in varactor diode-tuned microwave filters [PDF]

open access: yes, 2006
This paper examines the broadband distortion behavior in flexible filters employing varactor-diode tuning elements. Series- and parallel-resonant varactor-loaded transmission-lines, both commonly used in bandpass and bandstop microwave filters, are ...

Yield-Constrained Optimization Design Using Polynomial Chaos for Microwave Filters

open access: yesIEEE Access, 2021
Yield optimization aims at finding microwave filter designs with high yield under fabrication tolerance. The electromagnetic (EM) simulation-based yield optimization methods are computationally expensive because a large number of EM simulations is ...
