Dual-Band and Wideband Bandpass Filters Using Coupled Lines and Tri-Stepped Impedance Stubs [PDF]

open access: yesMicromachines, 2023
In this paper, two bandpass filters—one with a dual-band response and the other with a wideband response—were designed, implemented, and experimented with.

Narrowband and Wideband Bandpass Filters Based on Empty Substrate Integrated Waveguide Loaded With Dielectric Elements

open access: yesIEEE Access, 2021
Although several bandpass filters have been designed in the recently proposed empty substrate integrated waveguide (ESIW) technology to improve the quality factor and reduce losses with respect to those in SIW and planar technologies, all structures ...

Improved Designs for Highly Integrated Lowpass–Bandpass Filters

open access: yesIEEE Access, 2023
This study presents three dual-band lowpass–bandpass filters. The first handles lowpass and bandpass bands through its fifth-order and third-order Chebyshev filter responses, respectively.

Achieving accurate FTIR measurements on high performance bandpass filters [PDF]

open access: yes, 1998
The sources of ordinate error in FTIR spectrometers are reviewed with reference to measuring small out-of-band features in the spectra of bandpass filters. Procedures for identifying instrumental artefacts are described.

RF MEMS Based Tunable Bowtie Shaped Substrate Integrated Waveguide Filter [PDF]

open access: yes, 2015
A tunable bandpass filter based on a technique that utilizes substrate integrated waveguide (SIW) and double coupling is presented. The SIW based bandpass filter is implemented using a bowtie shaped resonator structure.

Parametrically enhanced bandpass filters

open access: yesIET Microwaves, Antennas & Propagation, 2021
This paper proposes a technique to enhance the quality factor (Q) of a resonator, which can then be used to realise bandpass filters (BPFs) with reduced insertion loss (IL) and improved passband selectivity.

Near millimeter wave bandpass filters [PDF]

open access: yesApplied Optics, 1981
The properties of bandpass filters for broadband photometry are reported in the 3-12-cm(-1) frequency range. The filters are based on a combination of capacitive grids deposited on thick Mylar substrates and are designed to have very high out-of-band rejection.

Millimeter-Wave Lumped Element Superconducting Bandpass Filters for Multi-Color Imaging [PDF]

open access: yes, 2009
The opacity due to water vapor in the Earth's atmosphere obscures portions of the sub-THz spectrum (mm/sub-mm wavelengths) to ground based astronomical observation.
