| Resumo: | Frequency selective surfaces (Frequency Selective Surface - FSS) are often used
in various applications in telecommunications. Some of these applications may require
that these structures have response with multiple resonance bands. Other applications
require that the FSS response have large frequency range, to meet the necessary
requirements. FSS to design with these features there are numerous techniques cited in
the scientific literature. Thus, the purpose of this paper is to examine some common
techniques such as: Overlap of FSS; Elements combined; Elements Elements
convolucionados and fractals. And designing multiband FSS and / or broadband
selecting simple ways in terms of construction and occupy the smallest possible space,
aiming at practical applications.
Given these requirements, three projects FSS were performed: a technology
applied to IEEE 802.11 a/b/g/n and two projects for application in UWB. In project
development, commercial software Ansoft DesignerTM and experimental results were
satisfactory was used |
