Comparación del efecto de la frecuencia de resonancia en los parámetros de dispersión para la antena septum en onda milimétrica

Abstract

This article details the comparison of the impact of the resonance frequencies of 60, 67 and 74 [GHz] in the dispersion parameters of three Septum-type antennas comprised in the millimeter wave band (mmW). The design was carried out using the Ansys software. of the antennas, the dimensioning and the variation of their construction materials, with the mathematical calculations the dimensions for the design of the three antennas were obtained, the same ones that are not reflected in the final design, so there is a frequency offset of 6% and a reduction in dimensions greater than 60% with respect to the adjustment, where the most relevant element of the antennas is the length of the horn, since it has an average phase difference of 80.97%. The results indicate that when increasing the resonant frequency from 60GHz to 74GHz there is a directly proportional relationship between the frequencies, so as the frequency increases, the values of the dispersion parameters and the phase shifts increase.
