A novel technique has been developed for measurement of dispersion and wavelength in microstrip transmission line laid down on an Al2O3 substrate. The frequency range so far investigated has been 4-12GHz, although the method could be satisfactorily used at far higher frequencies. The measurement accuracy is better than within 1%. Techniques for producing well matched transitions to any thickness substrate have also been established.read more

Microstrip Dispersion Model
TL;DR: The assumption that the quasi-TEM mode on microstrip is primarily a single longitudinal-section electric (LSE) mode leads to a transmission line model whose dispersion behavior can be analyzed and related to that of microstrip as mentioned in this paper.

A Frequency Dependent Solution for Microstrip Transmission Lines
TL;DR: Theoretical and experimental results of open microstrip propagation on both a pure dielectric and a demagnetized ferrite substrate are presented in this article, where a Fourier transform method is used to obtain the frequency dependence of phase velocity and characteristic impedance, and also the electromagnetic field quantities around the microstrip line.

Microstrip ring resonator and dispersion measurement on microstrip lines
Ingo Wolff,N. Knoppik +1 more
TL;DR: In this paper, a theory is described which takes into account the curvature of the microstrip ring resonator, which is shown to have a large influence on dispersion measurements on microstrip lines with small impedences.

Wideband Microstrip Ring Resonator Bandpass Filters Under Multiple Resonances
Sheng Sun,Lei Zhu +1 more
TL;DR: In this article, a new class of wideband microstrip bandpass filters under multiple resonances of an asymmetric ring resonator is proposed, where two capacitive coupling elements are placed at two perpendicular positions of a squared ring, whereas a pair of open-circuited stubs is formed in the symmetrical plane of these two excited ports similar to a dual-mode ring filter in shape.

Measurement of dielectric constant using a microstrip ring resonator
P.A. Bernard,J.M. Gautray +1 more
TL;DR: In this paper, an approach for measuring the permittivity of dielectric materials by means of a microstrip ring resonator is presented, which is used in conjunction with the variational calculation of the line capacitance of a multilayer microstriplike transmission line.
