Superconducting microstrip filters
AIP Conference Proceedings, 1978Control of the non‐zero radiation resistance inherent in metal strip transmission lines results in high‐currrent densities and low transmission quality factors. Superconducting metals reduce the ohmic losses to approximately the dielectric losses associated with a sapphire substrate. Quality factors of 100,000 are possible.

Microstrip Filter Designing by SRR Metamaterial
Wireless Personal Communications, 2013In this paper planar and compact band stop filter using split ring resonator (SRR) metamaterial is proposed. Band stop type attenuation is presented from L-to X-band. Low insertion loss in the pass band and high attenuation in the stop band can be considered as the advantage of this filter.

Tunable reflectionless microstrip bandpass filters
2018 IEEE Radio and Wireless Symposium (RWS), 2018A class of frequency-reconfigurable reflectionless microstrip bandpass filters is reported. This RF/microwave device is based on a complementary-duplexer architecture made up of a bandpass-type and a bandstop-type channel with resistive termination. Whereas the bandpass channel defines the transmission profile of the overall filter, the input-signal ...

Microstrip filter analysis using a microstrip waveguide model
Radio and Electronic Engineer, 1980The microstrip waveguide model has been successfully applied to a host of elementary discontinuity problems generally encountered in microstrip circuits. However, until now the efficiency of the model has never been proved for more complex distributed microstrip structures such as multiple element filters, where both the amplitude and the phase of the ...

Microstrip cascade trisection filter
IEEE Microwave and Guided Wave Letters, 1999A new configuration of odd-degree cascade trisection bandpass filter realized by combining a microstrip hairpin resonator and /spl lambda//2-line open-circuited resonator is proposed. The general asymmetric Chebyshev function is used to synthesize the cascade trisection prototype.

QUASI-ELLIPTIC MICROSTRIP FILTER
Issues of radio electronics, 2019Currently, modern telecommunication and radio-electronic systems widely use wireless information transmission technologies over the radio channel. Therefore, an urgent task is to ensure electromagnetic compatibility of a large number of simultaneously operating radio facilities using high-selective bandpass filters.

A Microstrip Nonreciprocal Tunable YIG Filter
IEEE Journal of Solid-State Circuits, 1968A nonreciprocal tunable YIG filter in a microstrip configuration has been constructed which makes use of a novel method of generating a circularly, polarized field in the plane of a microstrip circuit. Nonreciprocities in excess of 40 dB have been obtained at X band with relatively low insertion loss and VSWR.

Microstrip Filter with Extended Barrier
2019 Radiation and Scattering of Electromagnetic Waves (RSEMW), 2019The article describes the method and process of designing a interdigital bandpass filter on two two-stage microstrip resonators. As a result of the design, thanks to the introduction of two steps of different widths into the resonator, it was possible to double the barrier band by suppressing the parasitic bandwidth in the vicinity of the third ...

Narrowband microstrip HTS filter
2016 21st International Conference on Microwave, Radar and Wireless Communications (MIKON), 2016The new type of narrowband bandpass filter is presented. The design and realization of the filter in microstrip technology is described. The filter has been etched from YBCO thin film deposited on sapphire substrate. The filter has bandwidth of 0.2 %, RL better than 20 dB and a size of 2 inch in diameter.

Filtering Microstrip to Waveguide Launcher
2024 IEEE International Microwave Filter Workshop (IMFW)This paper presents a novel synthesis-based co-design of a filtering microstrip-to-waveguide launcher. The pro- posed design is intended to replace the waveguide low-pass filter generally placed between the common port of the diplexer and the antenna port in FDD communication systems. The launcher is truly considered part of the filter since it acts as
