Projeto de uma antena de microfita de alto ganho operando no modo TM100 para aplicações em 5G

Abstract

The need for people to be connected at all times and the increasing use of technology in different sectors of society, has caused an increase in demand for telecommunications services in recent years. It is extremely important to look for alternatives to optimize and increase the transmission capacity of communications networks. A great option is the fifth generation mobile networks (5G), as they allow high transmission rates. However, in this type of system the transmitted signal suffers a lot of attenuation when crossing obstacles, due to the use of high frequencies to guarantee a high data transfer rate. One way to solve this problem is to try to improve the gain of the antennas. An example of antennas widely used in radio frequency communications are rectangular microstrip antennas, as they are inexpensive and easy to manufacture. However, the typical gain of this type of antenna is in the order of 7 dBi ~ 8dBi. In this context, this work seeks to improve the gain of a rectangular microstrip antenna through a technique that consists of inserting four metallic pins symmetrically in the two diagonals of the resonator element, creating a short circuit with the ground plane. With the simple modification, an increase in gain of 2.36 dB was performed
