transmit frequency selective surface (FSS) is investigated. The FSS has good
frequency stability for both horizontally and vertically polarized waves incident
normally or at oblique angles. Due to its transmission for 900/1800/
1900 MHz mobile bands and good absorption for 5 GHz waves, it has the
potential as a security wall or isolator for 5 GHz WLAN systems. The absorption
in the stop band helps reduce additional WLAN multipath fading
caused by conventional reflecting FSS designs. The first layer of the FSS
consists of conventional conducting cross dipoles having a circular aperture
in the centre, while the second layer uses resistive cross dipoles. Moreover,
the conducting cross dipoles have been sandwiched between two dielectric
sheets to achieve a stable response for different angles of incidence. The periodicity
of both FSS layers is the same while the distance between the two
layers is reduced to one eighth of the free-space wavelength. This reduction
leads to a more compact design compared to the conventional Salisbury
screen, while still achieving acceptable absorption in the stopband. Both
theoretical and experimental results are presented to confirm the performance
of the absorb/transmit FSS.
