Abstract
Frequency Selective Surfaces have been applied in various ways in communication systems. More recently, these devices have been applied to improve indoor communication. In this paper, a study of angular stability and current density is performed on copper, silver and nickel FSS with FR4 and glass as substrate. A sample of glass used in building windows was characterized. The structure is designed to act as a spatial filter in the 2.45 GHz frequency, IEEE 802.11 b/g standard. The structures were simulated in Ansoft High Frequency Structure Simulator (HFSS) software version 19. The current density and angular stability of the proposed structures was analyzed. The element type chosen was the square loop, due to its good angular stability performance. The structures showed satisfactory angular stability performance. A change in current density was observed with the change of the conductive material.
