Antena de microfita de alto ganho e polarização circular com pinos de curto-circuito para aplicações em 5G

Abstract

This final paper presents a single-fed microstrip patch antenna with high-gain and circular polarization for applications in 5G cellular networks in the frequency range around 3.5 GHz. The antenna operates in fundamental mode and used a technique of inserting shorting pins between the resonator element and the ground plane to produce gain increment and circular polarization operation. The design was carried out in a simulation environment using the High-Frequency Structure Simulator module (HFSS) in the Ansys Electronics Desktop program. The results of these simulations show that the proposed antenna has a bandwidth for the reflection coefficient less than or equal to −10 dB from 3.43 to 3.68 GHz, which represents a bandwidth of 7.03% of the central frequency of operation, and maximum realized gain of 10.11 dBi at 3.51 GHz. With the results presented, it is believed that the proposed antenna is an interesting compact geometry for applications in 5G networks.
