Resumo: | In this dissertation three Yagi-Uda antennas were built, one with a frequency of operation of 2.4 GHz and the others operating at 24 GHz. Yagi-Uda antennas are well known, but here, printed Yagi-like prototypes were developed since nowadays most systems require printed circuits. Moreover, a comparison on the performance of a planar and a multilayer Yagi antenna was made, both operating in the mmWave region. Throughout the work it was possible to progressively improve gain and bandwidth, starting in the 2.4 GHz antenna and culminating in the multilayer prototype. These results were achieved without damage of the antennas’ global efficiency, which was kept at quite satisfactory values. |

As antenas Yagi-Uda são bastante conhecidas, no entanto, aqui, foram desenvolvidos protótipos impressos de antenas Yagi, já que, hoje em dia a maioria dos sistemas requer circuitos impressos. Mais ainda, foi feita uma comparação entre a performance de uma antena planar e a de uma antena multicamada, ambas a operar na região das ondas milimétricas. No decorrer do trabalho foi possível melhorar progressivamente tanto o ganho como a largura de banda das antenas, começando no protótipo de 2.4 GHz e culminando na estrutura multicamada. Estes resultados foram obtidos sem prejudicar a eficiência global das antenas, estando estes sempre em valores bastante razoáveis.2019-05-09T12:20:24Z2018-01-01T00:00:00Z2018info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10773/25997TID:202242196engRamos, Amélia da Silvainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-05-06T04:20:22Zoai:ria.ua.pt:10773/25997Portal AgregadorONGhttps://www.rcaap.pt/oai/openairemluisa.alvim@gmail.comopendoar:71602024-05-06T04:20:22Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
