Comparación de los parámetros de una antena dipolo de media onda en la banda de 26 GHz

Abstract

This article details the design and comparative analysis of the reflection coefficient, VSWR, gain and bandwidth parameters of a half wave dipole antenna operating in the 26 GHz millimeter wave band at the resonance frequencies: 24.25, 25.8 and 27.5 GHz. The study is carried out by modifying the dimensional parameters of the Medium Wavelength Dipole Antennas until they are tuned to the central frequencies. Once the antennas have been adjusted, a variation of materials is made with the 3 main conductors, silver, copper and gold to analyze the effect it produces on the dispersion parameters such as the reflection coefficient (𝑺𝟏𝟏), VSWR voltage standing wave ratio and radiation pattern. In the models already adjusted, the performance of the antenna improved, its bandwidth increased by 3.21%, a directly proportional relationship was also evidenced between the frequency and the VSWR parameters and (𝑺𝟏𝟏 ) without the antenna losing its dimensional properties as a dipole. half wavelength in the millimeter wave band. In this way, the results indicated a proportional and non-proportional relationship between the lags and the frequency where their key adjustments to achieve the desired values of (𝑺𝟏𝟏) and VSWR were to increase the dimensions of the radius parameter by 74, 80 and 150 times for the frequencies of 24.25, 25.8 and 27.5 GHz respectively and use as a conductor a material whose relative permeability is not below 0.999991
