Diseño de un arreglo de antenas tipo septum para banda de onda milimétrica

Abstract

This article presents septum type Nx1 line arrays composed of a group of antennas with identical characteristics that are adjusted for the millimeter wave band at a frequency of 60 GHz using the Ansys HFSS simulation software with an antenna limit of N = 4. In the 2x1 line array a gain of 2.8dB was obtained with a beam width of 212 °, the 3x1 line array a gain value of 4.5dB with a beam width of () and the 4x1 line array a gain of 4.9 dB and a beam width of 62 °, for this reason, a greater number of septum type antennas was determined, increases the gain compared to an individual antenna and its radiation pattern is more directive. Carrying out a comparative analysis between each arrangement, the 4x1 linear arrangement is identified as the best experimental fit with a reflection coefficient of S11 at -19.027 dB and VSWR of 1.951.
