Trabalho de Conclusão de Curso (Graduação em Engenharia Elétrica) - Departamento de Engenharia Elétrica, Universidade Federal do Rio Grande do Norte, 2023.https://repositorio.ufrn.br/handle/123456789/55731The purpose of this work is to design a microstrip antenna using niobium as a radiating element. The choice of this element is due to its excellent driving characteristics, especially at extremely low temperatures. At these temperatures, these types of antennas present good performance in terms of their main electromagnetic parameters. Comparative simulations were carried out in relation to copper, with the Ansys® Eletromagnetc HFSS simulator in the student version, identifying good performance in the reflection coefficient, better gain and radiation pattern, when the microstrip antenna is composed of niobium in its base. earth plane and its radiant element. Therefore, the use of niobium in this type of structure presented becomes a satisfactory alternative, especially in applications in which the device must operate in extreme negative climatic conditions, where niobium behaves as a superconducting element and is resistant to the corrosion process.Attribution 3.0 Brazilhttp://creativecommons.org/licenses/by/3.0/br/antena planar de microfitaplanar microstrip antennaelemento radiante supercondutorsuperconducting radiating elementnióbioniobiumbachelorThesisCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::TELECOMUNICACOES::TEORIA ELETROMAGNETICA, MICROONDAS, PROPAGACAO DE ONDAS, ANTENAS
