Abstract

The frequency selective surfaces (FSS) are drawn great interests for their wide range of applications. In this paper, a simple and compact shape for the FSS is proposed, in which the resonant element is a conducting strip that is folded into the shape of the letter-U and placed on a dielectric sheet. The folding of the strip reduces the element length to ½ of the effective wavelength, which is a considerable size reduction in comparison with other shapes. An example of the FSS was designed to reject the WiMAX frequency of 3.5 GHz and was investigated using the CST software package. The transfer characteristics were shown for the two cases of the vertical and horizontal polarizations of the incident electric field. The obtained rejection at the stopband was about 35dB. The obtained results are explained by considering the surface current distribution and electric field at the strip as well as the metamaterial behavior across the reject band. This approach gives better insight to understand the frequency selective property of the FSS.
