Interweaving the elements of a frequency selective surface (FSS) is a technique that allows wideband frequency filtering as well as size reduction. FSS structures using this method suit particularly to wireless indoor applications where the operating bands are spread over a wide spectrum. Interwoven square loop slots FSS have been designed, fabricated and measured. The FSS structure to be presented offers transparency at the emergency services band at around 400 MHz and suppresses most of the mobile and wireless bands up to 3GHz. The size of the unit cell developed is around 3% the corresponding wavelength, significantly smaller than a half wavelength resonant dipole.
