Equivalence between stepped-impedance ring and T-shaped cascaded transmission line network
2016 IEEE International Conference on Ubiquitous Wireless Broadband (ICUWB), 2016Two new equivalences in transmission line (TL) networks are proposed. The first one is found between a shunt fed stepped-impedance ring and a T-shaped TL network with a short-circuited series stub. Both the networks are composed of TL segments with the same electrical length. By using the Y and the ABCD matrices, an equivalent condition can be obtained,

Modeling of Slow-wave Si-BCB Transmission Line Loaded With Stepped Impedance Resonators
2019 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference (CSQRWC), 2019This paper presents a theoretical model of microwave slow wave transmission line with stepped impedance resonators. New equivalent circuit model is first presented for characterizing the slow-wave structure. Equivalent circuit parameters extraction and the effect of impedance ratio are studied.

High Spurious Suppression Bandpass Filter with Singly-Step Impedance Transmission Lines Compensation
2008 International Symposium on Communications and Information Technologies, 2008A simple technique to suppress spurious responses of microstrip bandpass filter is presented. This is achieved by employing the step impedance transmission line (SITL) compensated parallel-coupled line with enhance isolation/directivity to synthesis and implement the proposed bandpass filter. The optimum values of SITL parameters can be derive from the

Fourier coefficient design of stepped impedance transmission line networks
International Journal of Circuit Theory and Applications, 1973AbstractThe conventional method of designing stepped impedance transmission line networks from gain functions requires the use of a factorization process to obtain a passive input impedance, and then the application of Richards Theorem to determine the element values. A new technique is presented based upon the determination of the Fourier coefficients

2015 Asia-Pacific Microwave Conference (APMC), 2015
In this paper, a novel suspended stripline (SSL) bandpass filter using hybrid transmission line stepped impedance resonator (HTLSIR) is proposed. SSL has proven to be an excellent transmission-line system for realizing different types of filters. However, due to the effective permittivity being too close to unity, the size of the distributed elements ...

Journal of Physics D: Applied Physics, 2021
Abstract In this paper, a miniaturized tri-band bandpass filter (BPF) is proposed with a pair of quarter-wavelength shunted-line stepped-impedance resonators (SLSIRs). The resonant characteristics, high design freedom and tuning relationship of multi-dimension parameters of SLSIR are studied and applied to the tri-band design.

Proceedings of the Institution of Electrical Engineers, 1963
The coupling of two parallel transmission lines is utilized in directional couplers and filters which are simple to construct and have excellent electrical characteristics from high frequencies to microwave frequencies. The paper establishes the mathematical equivalence of such couplers to transmission-line stepped-impedance filters. It also places new
