Resumo: This work presents the study of spiral equiangular antenna applied as wideband irradiator element. A brief study about that geometry is presented. It appears in nature things and also at radiator elements applications. The equations was derived in order to evaluate such structures parameters. Some analysis from this model was made, searching the causes of its broadband performance. A few models are simulated establishing relationships between antenna's geometry and its radiation characteristics. A prototype was constructed with best results dimensions obtained through simulations. Two matching impedance structures were proposed, both of them developed by narrowing the width of a parallel strip transmission line. After several tests, it was decided to feed the prototype with no matching requirements, taking in to account that achieved radiation performance was good enough to meet expectations.

Foi feito um resumo hist?rico dos estudos envolvendo esta geometria, suas manifesta??es na natureza e sua aplica??o no projeto de antenas. Foram deduzidas equa??es para modelagem matem?tica destas estruturas, a partir das quais se desenvolveram an?lises te?ricas que justificassem sua grande largura de faixa. Foram simulados alguns modelos projetados com diferentes par?metros construtivos com o intuito de associ?-los ao desempenho da antena. O prot?tipo para execu??o dos ensaios utilizou as dimens?es que levaram melhores resultados nas simula??es. Para a excita??o da antena, se propuseram duas estruturas de casamento de imped?ncia, com varia??o da largura de uma linha de transmiss?o paralela. Ap?s v?rios testes, optou-se por excitar a antena sem cumprir todas as exig?ncias de casamento e balanceamento, tendo em vista que seu funcionamento sem estas estruturas foi considerado suficiente para as avalia??es de interesse nesta fase do desenvolvimento.Submitted by Tede Dspace (tede@inatel.br) on 2016-06-17T14:30:11Z No. of bitstreams: 2 license_rdf: 20592 bytes, checksum: 0c9b9c579af4cbbcf785ca803bd18d4b (MD5) Disserta??o V.Final Gabriel Lob?o.pdf: 3213542 bytes, checksum: c5c6c9eafcfb7bbd3d816b54a38ae9d8 (MD5)Made available in DSpace on 2016-06-17T14:30:11Z (GMT).
