Microstrip realization of ultraspherical filter function

2018 First International Colloquium on Smart Grid Metrology (SmaGriMet), 2018
In this paper the low-pass filter design procedure is revisited in order to convert ultraspherical polynomial function into physically realizable filter characteristics. The obtained characteristics is compared with Butterworth and Chebyshev characteristics and is shown to possess capability to design more classes of filters based on specifications ...

Microstrip band pass filter design

2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015
In this study, a microstrip structure has been suggested for use in open ring resonator microwave filter. This resonators are used in order to design a bandpass filter. Open ring resonator structures characterized by higher performance and have good frequency response for bandpass filters. Both resonator and band-pass filter is design with a simulation

Microstrip Filter Designing by SRR Metamaterial

Wireless Personal Communications, 2013
In 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.

Superconducting microstrip filters

AIP Conference Proceedings, 1978
Control 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.

Tunable reflectionless microstrip bandpass filters

2018 IEEE Radio and Wireless Symposium (RWS), 2018
A 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, 1980
The 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 ...

A novel microstrip loop filter

Microwave and Optical Technology Letters, 2005
Conventional loop filters often have large areas that are not fully utilized. To alleviate this problem, a novel elliptic-microstrip loop filter centered at 6.65 GHz and with a fractional bandwidth of 23% is proposed. The fabricated filter has a measured insertion loss of about 1.5 dB and a 0.6-dB ripple. © 2005 Wiley Periodicals, Inc.

A novel microstrip bandpass filter

Microwave and Optical Technology Letters, 2004
AbstractA novel compact microstrip bandpass filter which is realized by combining new slow‐wave effect with dual‐parallel coupling, is proposed. The filter is not only compact in size, but also has low insertion loss and sharp rejection. A demonstration filter is optimally designed and fabricated.

Narrowband microstrip HTS filter

2016 21st International Conference on Microwave, Radar and Wireless Communications (MIKON), 2016
The 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.

Optimization of microstrip filters tolerances

The Experience of Designing and Application of CAD Systems in Microelectronics, 2003. CADSM 2003. Proceedings of the 7th International Conference., 2004
The procedure of optimization of microstrip filter tolerances allowing for correlation of member tolerances is proposed. The filters realized on the basis of elements with lumped parameters are considered. The model for calculating tolerances is shaped by mapping transfer functions into the space of interval values.
