RESUMO:

The objective of this thesis is to present the analysis of new topologies of CPS, SIEW and FSS-EBG filters for wireless systems applications. The coplanar stripline (CPS) structure consists of two conducting strips loaded by two split ring resonators (SRRs), forming a CPS filter. The SIEW filter is based on the integrated E-plane waveguide substrate technology, being composed of several dielectric layers stacked with two resonant elements inside it, enabling selectivity with horizontal polarization. The third filter configuration consists of two periodic arrays formed by an FSS and an EBG, composing an integrated structure. The investigation of these structures was carried out by numerical analysis of the frequency response due to the variation of the physical parameters of the investigated geometries, identifying the attractive potentialities for microwave applications. The simulated results were obtained with the commercial software Ansoft HFSS and exhibited attractive characteristics as: reconfiguration, wide bandwidth, double band, simple design, light weight and easy manufacturing on a large scale. Some prototypes of the proposed devices were manufactured and the experimental results confirmed the validity of the used computational models. The experimental results were also compared with the simulated results, exhibiting a good agreement between them.
