Critical analysis of Frequency Selective Surfaces for dual band GSM-900 & 1800 MHz transmission

A critical analysis of various Frequency Selective Surface (FSS) structures like square, hexagonal and circular has been presented in this paper, which can be used to obtain a dual pass band for GSM 900 & 1800 MHz frequency. This analysis can be used to construct the FSSs for the better performance of mobile communication where energy efficient panes are used to isolate the area by restricting free passage of radiating waves, working as carriers of energy. The aperture type FSS allows the transmission of selected band frequencies. The simulation results provide an insight about the performance of these FSSs. The substrate used is teflon (ε

=2.1) and it is being considered as per the need of lesser thickness (1 mm) and providing flexibility so as to be incorporated over any individual surface.
