Resumo: | Smart antennas are sets or arrays of antennas, linked to a signal processor, capable of adjusting or adapting their own beam pattern in order to emphasize signals or directions of interest and minimize signals/interferences or directions that are not of interest. Fractal antennas are radiating structures generated recursively and iteratively from the repeated application of a generator set factor, having the basic characteristic of being self-similar, that is, its structure on a larger scale is similar to the structures of the same antenna on a reduced scale. Based on the theory of fractals developed by Mandelbrot, they find application in almost all branches of science. The present work seeks to unite these two innovative technologies, smart antennas and fractal antennas, which, combined, can be an excellent alternative in projects that require greater bandwidth, adaptive beamforming, miniaturization and increased base station capacity. An extensive bibliographic study was carried out to give greater support to the topic in question. In addition, Ansoft®'s HFSS computational tool, a software that simulates high frequency structures, was used to simulate the proposed intelligent fractal antenna. Several simulations are performed and the results carefully evaluated. In the end, an arrangement composed of intelligent fractal antennas was reached, capable of performing a good scan of space and, at the same time, operating in multiband, an indispensable requirement for modern 5G systems. It is expected that the proposed smart fractal antenna can contribute to the design of communication systems that require greater spectral efficiency, meeting the growing demand for faster, safer and more economical connections. |

Antenas fractais são estruturas irradiadoras geradas recursivamente e iterativamente a partir da aplicação repetida de um fator de conjunto gerador, possuindo a característica básica de ser auto semelhante, isto é, sua estrutura numa escala maior é semelhante à estruturas da mesma antena em escala reduzida.. Baseadas na teoria dos fractais desenvolvida por Mandelbrot, encontra aplicação em quase todos os ramos da ciência. O presente trabalho procura unir essas duas inovadoras tecnologias, as antenas inteligentes e as antenas fractais, as quais, combinadas, podem ser uma excelente alternativa em projetos que requerem maior largura de banda, formação de feixe adaptativo, miniaturização e aumento da capacidade de estações base. Um amplo estudo bibliográfico foi realizado para dar maior suporte ao tema em questão. Além disso, foi utilizada a ferramenta computacional HFSS da Ansoft®, um software que simula estruturas em alta frequência, para simular a antena fractal inteligente proposta. Várias simulações são realizadas e os resultados cuidadosamente avaliados. Ao final, chegou-se a um arranjo composto por antenas fractais inteligentes, capaz de realizar uma boa varredura do espaço e, ao mesmo tempo, operar em multibanda, requisito indispensável aos modernos sistemas 5G. Espera-se que a antena fractal inteligente proposta possa contribuir com o design de sistemas de comunicação que requerem maior eficiência espectral, atendendo à crescente demanda por conexões mais rápidas, seguras e econômicas.Universidade Federal de UberlândiaBrasilPrograma de Pós-graduação em Engenharia ElétricaCarrijo, Gilberto Aranteshttps://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4781864Y0&tokenCaptchar=03AIIukzgbWQHdyF5CoyS3qnsq8PMz1mDNsPaPM1XVwirnN3dwOMx7uJF6-o8LPMrMR4VRk2fspqMOBd3B_ckwEMgiU5lli0RS44LJ_DkjknUYF1jU9X1bDCXlpWYYEQmLIc61kefcdXGrHUHBv49_czzHD5KH0lF23cy5xcgYWLRa7HOh8xGvPtnj_XkSolwXH9HV31OE4Db2Cebwc2OHOeUPM8imowoo3clX55CEcgcNKULUcajW_xi3TjF0-_Wga0G2rM78TGmrdzmZAftmdw0BJA-yYdwlxMfvs3Wr96NjWR-oOupH-6JMqgZepW98uBa-fgJCv4d_kZz3TmMzK33wJTNQnJQWtSLkZRbuXNazq7besmOKmrK-EExFoJ6GtmUG7sq3xd3PwU6kZlcmjcbvcm9EsGAUhyn1dOWm7Qjl0F76_TDPSdV50vgYtPnmeC_GzUrIeTwHJqIIUaJLjnCIC3tLtr07XC-OFIwpzxKJcaowXHyezvEQSP6i1TN6gosbkXfBTX38cKhZa3qBwRuOa-5EM0miZwVasconcelos, Lorenço Santoshttps://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4859969E0&tokenCaptchar=03AIIukzi_IvKn704W_6F4RTs0N-qbXNxgZiYYpVXBJ80q-1guXKOqBYf5WE1M9l2w3O4YtyDaMxvUTLdvNVgFxp7kM1k_JFYgXm57bhCb5ORX414KgIOjSHM7yDAiKfIU-Te1yS_xkglm0dxv3VSZbBzfCvU9WZFhn1yK0UCnWOI-ByGdxscc3f2oaxenrObMxHrKYME8ZYo5VoKcNcWNCFAnFW72qP-WIPEtP6K2AHo97U87BRuUuF-Wi-xYmPU9E3fH-6BgVxn-KCeTrsHvYqemcFYSJi8jU4vObwZXVZXqxYH9V-RnfBWbIsEktTFGD36Jju6rxN537LPVdLSLakWbdehTC4TrZw-I4Y8LJVtB1rqTsTUe1sbocVzvOCMdyie5DV9nRUILo6ngnRXKl1eZWm64TOlXZ9amlY8y8FHbQh4lgGuRK-XJoOVmcQ8l_ScEc4zZG5TPVUhKS0QNAFnuDY0F4QS2jOWyncQg2Yh_rVwcOFa2di3H5Iu-zLQ0O9aCJgbL_y047dCE0M7gJ95IhscASCuxvwMateus, Alexandre Coutinhohttps://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4203252Y6&tokenCaptchar=03AIIukzj1d9OiwkZDjaOQ-RDqCAm4Pg_gKROAhlQX0FGs5XyelLYIVRqRAAMjGueL9DuN0QM_2z-Ds6hrgO6A-pZUbUT1eWJB8e1KZnpdQw8ZAigWULcNQ3BXBtXSdHrwU5jG7I4c_CGorWAXw2i3YY3EcXhDSmZsrg2xjzwn0x395rvgQQiI2mGLe91-_Wv9PdOYWPCxIRqmekzPGhyvX3Yp7nW7rXWXvVYdXUupdqBvgZEQ_8UrKtSvwgp0Hq26z_iZ9Bv2h8ES_Ch78zXJFx_J8FWzAt5K99V9sdIdcrvZcTv2hbrqh_l5YvjkWDd7auFoGZtIP_gfGMhmsznnXMFnTJg3Ht4bO77KcuZaSXHvDZDhZyol0kLu1O5Sl-59fn6lJw-tvXJgulEr2QrCbUJ2TCA9ipSN4P2yrocjDwu5tGyWmFWox7jFdf_vA7a8aaYZawo7KSw5IK-DUwoZHixk6pzcoX4SL7KhDmDhndyB8fPQ1-MEBQ4qCJyapdurRnhed-V--nQ1SiqHRg5J4fEGG0SX55ABWQRibeiro, Daniel Luiz2022-10-25T13:51:40Z2022-10-25T13:51:40Z2022-10-07info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfRIBEIRO, Daniel Luiz.

Smart antennas are sets or arrays of antennas, linked to a signal processor, capable of adjusting or adapting their own beam pattern in order to emphasize signals or directions of interest and minimize signals/interferences or directions that are not of interest. Fractal antennas are radiating structures generated recursively and iteratively from the repeated application of a generator set factor, having the basic characteristic of being self-similar, that is, its structure on a larger scale is similar to the structures of the same antenna on a reduced scale. Based on the theory of fractals developed by Mandelbrot, they find application in almost all branches of science. The present work seeks to unite these two innovative technologies, smart antennas and fractal antennas, which, combined, can be an excellent alternative in projects that require greater bandwidth, adaptive beamforming, miniaturization and increased base station capacity. An extensive bibliographic study was carried out to give greater support to the topic in question. In addition, Ansoft®'s HFSS computational tool, a software that simulates high frequency structures, was used to simulate the proposed intelligent fractal antenna. Several simulations are performed and the results carefully evaluated. In the end, an arrangement composed of intelligent fractal antennas was reached, capable of performing a good scan of space and, at the same time, operating in multiband, an indispensable requirement for modern 5G systems. It is expected that the proposed smart fractal antenna can contribute to the design of communication systems that require greater spectral efficiency, meeting the growing demand for faster, safer and more economical connections. |
