RESUMO:

This work proposes new geometries of Bioinspired Frequency Selective Surfaces (BFSS) for applications in wireless communication systems, namely C and Ku bands, and Ultra Wideband (UWB). Single and coupled BFSS geometries are considered. The geometry of the BFSS array element has the shape of a four-leaf clover, and showed a dual-band response, with operating frequencies at C and Ku bands. For the development of the BFSS with ultra-wideband response, a cascade structure is developed, in which an FSS with square ring patch elements is coupled to a BFSS. Ansoft HFSS software is used in the simulation and design of the considered bioinspired FSS geometries. Prototypes are fabricated and measured. Simulation and measurement results are in good agreement. In addition, the angular stability of the BFSSs is investigated.
