Comparación de una antena dipolo con una antena de dos dipolos para banda de ondas milimétricas

Abstract

This article develops the comparison between a single dipole antenna and a double dipole antenna. The study was carried out using the ANSYS HFSS software, where the simulations of the proposed designs of the antennas were carried out, the same ones that will work in the millimeter wave band (MMW) specifically at a frequency of 60 GHz. The radiation lobes of both radiating systems they are similar since there is a slight variation in the gain of each angle in the Phi (Φ) plane. The investigation shows the different shapes, elements and materials that make up each antenna. It was determined that the double dipole antenna presents a higher performance compared to the single dipole antenna, since the values of S11 is -23.01 dB, the BW is 8.22 GHz and the VSWR is 1.22, these data are better in each simulation compared to the values of the single dipole antenna resulting in an S11 of -21.40 dB, the BW of 6.05 GHz and the VSWR of 1.48.
