Dielectric resonator bandstop filters [PDF]
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.

Dielectric resonators and filters for cellular base-stations [PDF]
The investigation into three types of dielectric resonators for use in base-station filtering applications is presented. The triple-mode cubic TE016 resonator is shown to have good performance for high Q applications.

Micromachined microwave filters [PDF]
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 ...

Combined signal‐interference/split‐type microwave multi‐band bandpass filters
Two classes of RF/microwave planar quad‐band bandpass filters (BPFs) that simultaneously exploit transversal signal‐interference and multi‐passband‐splitting mechanisms are reported.

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

SNAP microwave optical filters [PDF]
If the originally flat bottom of a wide quantum well with multiple eigenstates is periodically modulated, its eigenvalues rearrange into denser groups separated by wider gaps. We show that this effect, if implemented in an elongated bottle microresonator [also called a surface nanoscale axial photonics (SNAP) microresonator] allows us to design ...

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 ...

Yield-Constrained Optimization Design Using Polynomial Chaos for Microwave Filters
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 ...
