Previous issue date: 2012-05-18 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / This work presents a theoretical, numerical and computation analysis of
parameters of a rectangular microstrip antenna with metamaterial substrate, fin line as a
coupler and also integrated devices like integrated filter antenna. It is applied theory to
full-wave of Transverse Transmission Line - TTL method, to characterize the
magnitude of the substrate and obtain the general equations of the electromagnetic
fields.
About the metamaterial, they are characterized by permittivity and permeability
tensor, reaching to the general equations for the electromagnetic fields of the antenna.
It is presented a study about main representation of PBG(Photonic Band Gap)
material and its applied for a specific configuration.
A few parameters are simulated some structures in order to reduce the physical
dimensions and increase the bandwidth. The results are presented through graphs. The
theoretical and computational analysis of this work have shown accurate and relatively
concise. Conclusions are drawn and suggestions for future work / Este trabalho apresenta a an?lise te?rica, num?rica e computacional dos
par?metros de uma antena de microfita do tipo retangular sobre substrato metamaterial,
linha de laminas na forma de acoplador e tamb?m de estruturas integrada como a antena
filtro integrada. ? aplicada a teoria de onda completa do m?todo da Linha de
Transmiss?o Transversa - LTT, para a caracteriza??o das grandezas do substrato e
obten??o das equa??es gerais dos campos eletromagn?ticos.
Sobre o metamaterial, os mesmos s?o caracterizados atrav?s de tensores
permissividade e permeabilidade, chegando-se ?s equa??es gerais para os campos
eletromagn?ticos da antena.
? apresentado um estudo das principais representa??es do material PBG
(Photonic Band Gap) e suas aplica??es para determinadas configura??es.
S?o simulados v?rios par?metros de algumas estruturas com o intuito de
diminuir as dimens?es f?sicas e aumentar a largura de banda das mesmas. Os resultados
s?o apresentados atrav?s de gr?ficos. A an?lise te?rico-computacional desse trabalho se
mostra precisa e relativamente concisa. S?o apresentadas as conclus?es e sugest?es para
trabalhos futuros
