Mechanically Reconfigurable Microstrip Lines Loaded with Stepped Impedance Resonators and Potential Applications [PDF]
International Journal of Antennas and Propagation, 2014 This paper is focused on exploring the possibilities and potential applications of microstrip transmission lines loaded with stepped impedance resonators (SIRs) etched on top of the signal strip, in a separated substrate. It is shown that if the symmetry

IEEE Sensors Journal, 2021 Reflective-mode step-impedance transmission line based sensors for dielectric characterization of solids or liquids have been recently proposed. In this article, in order to further increase the sensitivity, the sensor is implemented in coplanar waveguide (CPW technology), and this constitutes the main novelty of this work.

Influence of the line characterization on the transient analysis of nonlinearly loaded lossy transmission lines [PDF]
, 1994 The analysis of nonlinearly terminated lossy transmission lines is addressed in this paper with a modified version of a method belonging to the class of mixed techniques, which characterize the line in the frequency domain and solve the nonlinear problem

Miniaturized tri-notched wideband bandpass filter with ultrawide upper stopband suppression
Scientific Reports, 2021 Stepped impedance resonator (SIR) and its derivative resonators are widely used in the design of microwave filters. However, many spurious modes will be introduced into the stopband, resulting in lower upper stopband suppression and performance ...
