Efeito da inclinação do plano de terra para antenas de microfita multicamadas com elementos parasitas fractais. 2011. 95 f.

This antenna consists of three dielectric layers arranged vertically on each other, using feeding microstrip line in patch 1, of the first layer, which will feed the remaining patches of the upper layers by electromagnetic coupling. The objective of this work is to analyze the effects caused by increase of the angle of inclination of the ground plane in some antenna parameters such as return loss, resonant frequency, bandwidth and radiation pattern. The presented results demonstrate that with the increase of the inclination angle it is possible to get antennas with characteristics multiband, with bigger bandwidth, and improving the impedance matching for each case analyzed, especially the larger angleapplication/pdfAcesso AbertoAntena de microfitaPlano de terraMulticamadas elétricasAcoplamento eletromagnéticoMicrostrip antennaGround plane inclinedMultilayer electricalElectromagnetic couplingmasterThesisCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA
