Switchable and tunable band stop filter

2017 Progress In Electromagnetics Research Symposium - Spring (PIERS), 2017
In this paper, we present the design and fabrication of switchable and tunable thin film bulk acoustic wave resonator (FBAR) and stop band filter based on Barium Strontium Titanate (Ba .07 Sr 0.3 TiO 3 ) deposited by metalorganic decomposition method (MOD).

Computational Efficiency of Interpolated Band-Stop Filters

2020 1st International Conference Problems of Informatics, Electronics, and Radio Engineering (PIERE), 2020
A structure of an interpolated band-stop FIR filter is proposed. Relations of computational efficiency, increase of many registers, optimal interpolation coefficient, and maximum computational efficiency coefficient depending on the width of stop and transition bands are obtained.

Band-stop Filter Design of Coplanar Stripline

2007 Asia-Pacific Microwave Conference, 2007
In MIMO system, the effect of mutual coupling between the antennas influences and often deteriorates the transmission capacity of the wireless communications. In this paper, band-stop filters using spur-line and CPS structures between two antennas are proposed to reduced the effect of the coupling.

Compact microstrip band-stop filter using IDCLLR

2010 International Conference on Microwave and Millimeter Wave Technology, 2010
The structure of inter-digital capacitance loaded loop resonator (IDCLLR) is employed for designing microstrip (MS) band-stop filter (BSF), it benefits from its miniaturization and design flexibility due to more structural parameters. Three kinds of IDCLLR-based MS-BSF are presented in this article.

Multiple-band waveguide based band-stop filter

International Journal of Applied Electromagnetics and Mechanics, 2015
This paper presents a novel transversal coupling network for the design of multiple-band bandstop filters. In this proposed structure, multiple-band bandstop filter is design based on amalgamated (conductive and dielectric material) posts coupled rectangular waveguide to demonstrate the feasibility of proposed network.

Magnetically Tunable Band-Stop Filters

IEEE Transactions on Microwave Theory and Techniques, 1965
Techniques for the design of magnetically tunable band-stop filters using ferrimagnetic garnet resonators (such as yttrium-iron-garnet spheres) are presented. Design for prescribed response, starting from a low-pass lumped-element prototype filter is outlined.

Tunable Coplanar Wave Guide Band Stop Filters

Integrated Ferroelectrics, 2013
A tunable band stop filter is designed in the frequency range of 0.5 GHz to 1 GHz and its performance is simulated with Agilent ADS. The filter is fabricated on FR-4 substrates. The BST parallel plate ferroelectric varactors are fabricated on sapphire substrates by MOD technique with Platinum Electrodes and ion-milling.

Bifunctional co-design of liquid crystal phase shifter and band-stop filter

Journal of Physics D: Applied Physics, 2019
In this paper, a new co-design approach for a bifunctional band-stop filtering tunable phase shifter is proposed. The bifunctional microwave component consists of a tunable liquid crystal phase shifter (LCPS) and a band-stop filter. It can simultaneously

Tunable high-frequency band-stop magnetic filters

Applied Physics Letters, 2003
We present results on Fe- and Permalloy™-based microstrip microwave band-stop filters. These structures, prepared on GaAs substrates, are compatible in size and growth process with on-chip high-frequency electronics. We observed power attenuation of 100 dB/cm for Permalloy and 180 dB/cm for Fe. The insertion loss is low: 2–3 dB for Permalloy and 3–5 dB
