Análisis de parámetros de dispersión de una antena logarítmica periódica para banda de onda milimétrica

Abstract

This article describes the design and behavior of a log periodic dipole array antenna (LPDA) that works in the millimeter wave range, at a frequency of 60 GHz; the different dispersion parameters are analyzed, such as the reflection coefficient that have a limit of -20 dB, VSWR in a range of 1 to 1.5 dB and radiation pattern; For this, the ANSYS HFSS software is used, which allows the use of a variety of materials and shapes, to simulate the antenna structure (substrates and dipoles), as well as different tools for the analysis of the aforementioned dispersion parameters, this in order to find the most relevant design, ; the best operating frequency found is 60.0125 GHz, with reflection S11=-228063 dB, VSWR=1.2598 dB and a directive radiation pattern with G=8.30 dB.
