Análisis del cambio de material en el coeficiente de reflexión y VSWR en una antena dipolo de media onda en la banda de mmW

Abstract

In this paper, we will compare the material impact for half-wave dipole antennas using copper and aluminum materials. We start by designing an antenna with a frequency of 38.75 GHz for both antennas, once this is achieved, we will configure the copper and aluminum materials of construction to analyze the influence it has on the VSWR, S11 and radiation pattern parameters. In this study, the aluminum and copper materials are efficient since both are good dielectric conductors, so when performing the comparative analysis of the parameters adjusted to the designed model, it is visualized that the aluminum material produces a wider bandwidth than copper and allows a higher data transmission. Therefore, within the scope of the study, aluminum is the best material because it has a better performance, which makes it a better candidate for the transmission of information, since the level of permittivity and conductivity gives better results in its bandwidth.
