This paper presents the design analysis of five vertical shielded microstrip lines. The vertical microstrip transition solves the problem of discontinuity between two microstrip lines in different layers of microwave circuit. The main objective of this paper is to compute the capacitance and other relevant parameters like potential distributions of five shielded vertical microstrip line by usin...

This paper presents an EM analysis of dispersions & discontinuities in a microstrip transmission lines. Dispersion characteristics of a microstrip lines are investigated by the existing models for study of microstrip lines and then compare the results with Software Simulation. Dispersions on microstrip lines with characteristics impedance 50Ω are investigated for the frequency range 1 to 18 GHz...

Abstract—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 in...

The scattering of a diaphragm in a packaged microstrip line is investigated using the mode-matching method together with the method of lines. Instead of analyzing the discontinuity in the microstrip, this paper tackles the variation of the waveguide housing. The influences of the thickness and the depth of the diaphragm on the scatterings of the dominant mode and higher-order modes are analyzed...

AbstructThe equivalent circuit and the scattering parameters of the orthogonal microstrip crossover discontinuity are determined by assuming that the conducting strips are embedded in a multilayered substrate which may contain both anisotropic dielectrics and materials with a nonnegligible conductivity. The equivalent circuit of the crossover is obtained in terms of the complex excess charge de...

The space-domain integral equation method using the generalized scattering matrix description of microwave passive circuits is employed to investigate the mode conversion of a CBCPW open-end discontinuity with unequal side plane widths. The conversion into two additional dominant modes, the c-modelike mode and the -mode-like mode, and into the transmitted microstrip mode from an incident CPW mo...

Abstract High-speed and high-frequency PCB interconnect solutions with the slightest discontinuities in physical geometry along microstrip transmission line can significantly degrade integrity of signal being transferred. This paper presents an analysis SMT component pads their impact on successive impedance. During 0805, 1206 2512 package size pad discontinuity evaluations it was spotted, that...

The low pass filter is used in many application of microwave communication. Therefore it is necessary to design a good low pass filter for the faithful reproduction of wanted signals. Previously used methods to design the low pass filter using insertion loss method don’t give a very good flat response. So, a new method has been proposed for the filter design which gives a good response as compa...
