Resumo: This work presents the development of printed antennas using the multifractal geometry of the Cantor?s comb. In this configuration, the models use different ratios in each iteration of the fractal and allow operation in multiple frequency bands, with different results from those achieved under traditional iteration conditions. We discuss changes in order to extend the op-erating range around the resonance conditions. Along the development, the proposed struc-tures were simulated with HFSS? software and then some models were tested in laboratory. We analyze characteristics related to the reflection coefficient, irradiation patterns, gain, di-rectivity and radiation efficiency of the antennas. The prototypes were made of glass fiber FR4 and polytetrafluoroethylene laminates. It is proposed a compact model with dimensions of 76mm?38mm?0.9mm which performs within acceptable limits in the range between 3GHz and 20GHz

Nesta configura??o, os modelos empregam raz?es diferentes em cada itera??o do fractal e possibilitam opera??es em m?ltiplas faixas de freq??ncias, com resultados diferentes dos alcan?ados sob condi??es tradicionais de itera??o. Discutem-se alte-ra??es com a finalidade de ampliar a faixa de opera??o em torno das condi??es de resson?ncia. Para o desenvolvimento, as estruturas propostas foram simuladas no programa HFSS? e, pos-teriormente, realizaram-se ensaios em laborat?rios de alguns modelos. Analisam-se caracter?s-ticas referentes ao coeficiente de reflex?o, diagramas de irradia??o, ganho, diretividade e efi-ci?ncia de irradia??o das antenas. Os prot?tipos foram constru?dos com laminados de fibra de vidro FR4 e de politetrafluoretileno. O modelo final apresenta dimens?es compactas de 76mm?38mm?0,9mm com desempenho dentro dos limites aceit?veis na faixa entre 3GHz e 20GHz.Submitted by Tede Dspace (tede@inatel.br) on 2016-06-27T17:25:54Z No. of bitstreams: 2 license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Disserta??o V.Final Ma?ra Santos.pdf: 1986032 bytes, checksum: e7b1851ca801af708be3575a55390d6b (MD5)Made available in DSpace on 2016-06-27T17:25:54Z (GMT).
