Análise de antenas CPW e CPS e de FSS com geometrias fractais para sistemas de comunicação sem fio. 2018. 62f. Dissertação (Mestrado em Engenharia Elétrica e de Computação) - Centro de Tecnologia, Universidade Federal do Rio Grande do Norte, Natal, 2018.https://repositorio.ufrn.br/jspui/handle/123456789/26127The main objective of this work is the simulation of CPW and CPS structures for the design of new CPW and CPS antennas with fractal elements for operation in the 1 GHz to 14 GHz band, aiming at applications in multiband, wide band and ultra-wideband (UWB). In addition, the characteristics of radiation, gain and polarization of the antennas are observed. Computational simulations are performed and several conFigurations of CPW and CPS antennas and FSS are designed using Ansoft HFSS software. For purpose of comparison with the simulated results, several prototypes of CPW and CPS antennas are manufactured and measured. FSS structures are also designed, simulated and measured. The experimental results show a good agreement with the results of the numerical simulations performed for both antennas and FSS.Acesso AbertoAntena CPWAntena CPSAntenas fractaisAntenas compactasComunicações sem fioFSSSuperfícies seletivas de frequênciamasterThesisCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA
