A Compact Band-Reject Frequency Selective Surface with Stable Response for Wimax Applications

Abstract

In this letter, a new design of compact band-reject frequency selective surfaces is proposed. Compared to previous compact structures, the FSS proposed has a better compact performance with the dimension of a unit cell only 0.082λ × 0.082λ where λ represents the wavelength of the resonant frequency. Above design rejects Wimax band (3.3-3.8) GHz. Moreover, the proposed design has a stable response with respect to different polarization characteristics and different incident angles of the incident plane wave. The squashed performance can further be improved by changing width of patch. The design is aimed at the rejection of Wimax band.
