Diseño de un arreglo de nanoantenas para la banda de los Terahercios

Abstract

In this paper, the performance between a microstrip nanoantenna and a 2x1 linear nanoantenna array in the far infrared light waveband at a frequency of 3.3 THz was analyzed by numerical simulation. In the nanoantenna, a gain of 2.43 dB was obtained with a HPBW of 109.5 deg, while in the 2x1 arrangement a gain of 6.23dB was achieved with a HPBW of 98.1 deg, where an increase in directivity of 3.8Db is observed, achieving a better range. As the number of antennas is increased, an increase in gain compared to a single antenna is achieved, while at the same time a more focused radiation pattern is obtained. When carrying out a comparative analysis of the increase of antennas in each linear configuration, an increase in the reflection coefficient S11 is observed in comparison with the individual nanoantenna
