A SIMPLE AND NOVEL MODEL FOR EDGED MICROSTRIP LINE (EMTL (original) (raw)
Modeling and simulation of shielded microstrip lines
2007
Microstrip lines are the most commonly used transmission lines at high frequencies. Modeling and simulation of microstrip lines becomes essential technique to investigate. In this paper, we illustrate how to model and simulate the capacitance of rectangular coaxial lines using COMSOL, a finite element software. We also determine the capacitance coupling of the single-strip, double-strip, three-strip, six-strip, and eightstrip shielded microstrip lines. We compared our results with those obtained by other methods and found them to be close.

This paper presents the model which is developed for single and coupled microstripline structure for both the even and odd-mode of propagation of waves. Most important and common models are: Conformal transformation model, coupled analysis model, hybrid analysis model, numerical analysis by relaxation model, even and odd-mode models, which is the outcome of the coupled line model. H.A. Wheeler derived the characteristic impedance and propagation parameters. Numerical methods are adopted by Stenelhalfer and Sylvester based on pure TEM-mode, Quasi-TEM mode and Non-TEM mode. © 2015 Elixir All rights reserved.

Transmission line model for analysis of microstrip travelling wave antennas with right angled bends
AEU - International Journal of Electronics and Communications, 2018
A simple but accurate transmission line model for the analysis of microstrip travelling wave antennas based on microstrip lines and right angle bends is described. Radiated far fields from the antenna are calculated using magnetic current on the antenna sidewalls and electric current on the strip surface. Local reflections from the right angle discontinuity are considered in internal field calculations. An equivalent decay constant to accommodate the radiated power from the antenna is introduced which is iteratively computed to improve impedance and radiation characteristics calculated by the model.
EM FIELD COUPLING TO NON-UNIFORM MICROSTRIP LINES USING COUPLED MULTI-CONDUCTOR STRIPS MODEL
Progress in Electromagnetics Research B, 2009
A model for the two-dimensional analysis of microstrip lines, named Rigorously Coupled Multi-conductor Strip (RCMS) is introduced. In this model, the width of the strip of a microstrip line is subdivided into a large number of rigorously coupled narrow strips. So, a microstrip line can be considered as a coupled multi-conductor transmission line. Determination of the capacitance and inductance matrices of the model is introduced, also. The voltages and currents induced by electromagnetic fields for the coupled multi-condutor strips problem can be obtained using Bernardi's method. The effect of an external EM wave on a microstrip line with non-uniformity in its width is computed by adding the circuit model of transverse discontinuity (narrow slit) to the RCMS model. Finally, the validity and efficiency of the introduced method is investigated using previous work and full wave EM-simulation software.

In this present paper we studied about the variation of phase shift of the wave travelling through the microstripline with the geometry of the structure and frequency. The simple and most significant transmission structures are stripline, microstripline and their variants have been proved to be significant in transmitting the signals from one place to remote corner of the world. Microstripline is the modified form of stripline and is most simple and useful in giga hertz range of frequency from 20 – 30 GHZ. This study brings the world closer together via exchange of information by linking the satellites communications and networking. This makes the defence system too much intelligent and smart.
