Abstract

A high optical transparent and wireless communication band-pass window with hexagon-loop aperture ITO frequency selective surface (FSS) array structure is developed. The parameters of hexagon-loop aperture FSS are designed as h = 5.5mm, w = 0.5mm, d = 2mm according to empirical formula of resonance frequency. The bandpass filtering characteristics of different dielectric-loaded FSS windows with the same dielectric thickness e=0.5mm are simulated and comparatively analyzed. Through calculation results and simulation analysis, it can be found that single-layer dielectric-loaded FSS windows have more stable and desired resonance frequency of 5.8GHz, wider symmetrical bandwidth and independence of incidence angle and polarization than that of double-layer ones at large incidence angles. So it can be concluded that single-layer dielectric-loaded FSS windows are suitable for ISM wireless communication bandpass filtering application.
