Abstract

Frequency selective surfaces (FSSs) with fractal four legged aperture elements are studied. Three different order fractal elements are discussed for comparison. The results show that by using this novel kind of elements, multiband FSSs with miniaturized elements can be achieved. The ratio of the first resonant wavelength to the periodicity can be up to 10.36. Four passbands for normal incidence or two stable passbands for different incident angle and polarizations can be obtained. The FSS is analyzed by the spectral domain approach.
