Comparación de los parámetros de dispersión de la antena dipolo doblada para las frecuencias de 24.25, 25.8 y 27.5 GHZ

Abstract:

The purpose of this research is to carry out the analysis and comparison of the dispersion parameters of a bent dipole antenna in the 24.25, 25.8 and 27.5 GHz frequency bands, the same ones that were designed and simulated in the ANSYS HFSS software. A mathematical model was built from its theoretical formulas, which was subjected to modifications in its physical dimensions such as: size of arms, dielectric, etc., in order to tune the resonance frequency, thus obtaining an adjusted model for comparison. of the gap in the dispersion parameters that exists between these two models. It was shown that in the adjusted model, an almost ideal VSWR was achieved, since it is close to 1, it was also visualized that there is a greater phase shift in the frequency of 25.8 GHz, when working with an air dielectric, since it gives as resulting in a phase shift of approximately 276.96% in the radius, it was shown that the dimensions of the dielectric, in some cases it is necessary to modify to tune the resonance frequency. The phase shift of the resonant frequency for both the porcelain and air dielectric increases as the frequency increases.
