Análisis comparativo del comportamiento de los parámetros de dispersión para la antena tipo CURL en la banda de frecuencias de 60, 67 Y 74 GHz

Abstract

This work develops the design of three curved sheet antennas working at 60, 67 and 74 GHz, starting from the antenna design theory and using the high frequency design software "ANSYS HFSS" and "Advanced Design System", to make the respective adjustments in the dimensions of the antenna elements to analyze the behavior of the dispersion parameters. Three designs were made, using materials such as: copper, aluminum and gold for the conductors and fiberglass, bakelite and porcelain for the substrate. Where it was determined that the best materials are copper and fiberglass. Based on the adjustments of each design, it was observed that the frequency has a direct impact on the dimensions of the antenna elements and on the dispersion parameters. In addition, it was identified that the most significant element of the antenna is the transmission line, since it presents an average phase difference of 167% between its mathematical and adjusted dimensions to achieve the proposed objectives, with the results obtained, it was concluded that the antenna works efficiently in the millimeter wave band.
