Diseño y análisis del SAR con una antena dipolo doblado en la banda 5G

Abstract

This article is based on the analysis of Specific Absorption Rate (SAR) through the design of a folded dipole antenna operating at a frequency of 6 GHz and with a characteristic impedance of 275 ohms. The goal is to determine significant SAR levels on a human hand at close, medium, and far distances from the antenna, with different inclination angles of 0°, 90°, and 270°. The obtained results show that as the antenna gets closer to the hand, the SAR value increases, reaching maximum values of 52.6317, 9.1081, and 32.6108 [W/kg] at a distance of 5mm. The ideal value is obtained with an inclination angle of 90° at medium and far distances, with SAR levels of 3.3953 and 3.5931 [W/kg], respectively. It is important to note that depending on the angle and distance from the hand, these values may fall within or outside the recommended range by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).
