High Performance of the Coaxial Cable Based on Different Dielectrics

Abstract

This paper presents the analysis of high performance for coaxial cable with different parameters. The modeling for performance of coaxial cable contains many parameters, in this paper will discuss the more effective parameter is the type of dielectric mediums (Polyimide, Polyethylene, and Teflon). This analysis of the performance related to dielectric mediums with respect to: dielectric losses and its effect upon cable properties, dielectrics versus characteristic impedance, and the attenuation in the coaxial line for different dielectrics. The analysis depends on a simple mathematicalmodel for coaxial cables to test the influence of the insulators (Dielectrics) performance. The simulation of this work is done using Matlab/Simulink and presents the results according to the construction of the coaxial cable with its physical properties, the types of losses in both the cable and the dielectric, and the role of dielectric in the propagation of electromagnetic waves. Satisfied results are obtained that concluded the condition of high performance for coaxial cable
