A HYBRID METHOD FOR THE COUPLING ANALYSIS OF MULTICONDUCTOR TRANSMISSION LINES EXCITED BY DIPOLE ANTENNA

Ultra Wideband Monopole Antenna Excited by a Capacitive Coupling Feed with Double Band Notch Function

This paper presents the results of a new monopole antenna that exhibits 2.75-10.7 GHz performance. The proposed antenna consists of a radiating patch with notches excited by capacitive coupling feed. Also, the antenna’s truncated ground-plane incorporates a central notch. This modification significantly improves the antenna’s impedance bandwidth by 118% over an ultra-wideband frequency range. T...

Transient analysis of lossy multiconductor transmission lines model based by the characteristics method

In this paper, we will present a low losses multiconductor transmission lines model valid both in the time and the frequency domains. This model is an extension of the characteristics method (Branin method) valid for lossless lines. Our model permits to describe the line as a quadripole whose advantage is to avoid the presupposed applied charges conditions in its extremes. This permits it to be...

Analysis of Multiconductor Quasi-TEM Transmission Lines and Multimode Waveguides

This paper presents an analysis approach of multicondcutor quasi-TEM lines transmission interconnect in a single dielectric region and multimode waveguides using the finite element method (FEM). We illustrate that FEM is suitable and effective as other methods for modeling of interconnecting lines in highspeed digital circuits. We mainly focus on designing of five-conductor transmission lines i...

Wavelet-Based Adaptive Solution for the Nonuniform Multiconductor Transmission Lines

A time-domain technique for the solution of arbitrary nonuniform multiconductor transmission lines (NMTL’s) is presented. The technique is based on a weak formulation of the NMTL equations obtained through spatial expansion of the voltage and current vectors into biorthogonal wavelet functions. Wavelets allow adaptive representations of the solution by using few expansion coefficients, with any...
