A Miniaturized Flexible Frequency Selective Surface for X-Band Applications
TLDR
In this article, a band-stop frequency selective surface (FSS) is proposed to provide effective shielding in X-band, with attenuation of at least 56 dB, and the proposed FSS provides 3-dB fractional bandwidth of 48% which is necessary to cover Xband.Abstract:
In this paper, a novel and miniaturized band-stop frequency selective surface (FSS) is presented. This FSS provides effective shielding in X-band, with attenuation of at least 56 dB. The proposed FSS provides 3-dB fractional bandwidth of 48% which is necessary to cover X-band. Moreover, the proposed design is polarization independent as it provides a stable frequency response at normal and oblique angles of incidences for both perpendicular TE and parallel TM wave modes. The copolarized and cross-polarized scattering parameter $S_{21}$ is analyzed at the selected band-stop/notch frequencies. More importantly, the proposed FSS is suitable for conformal applications and hence finds wider employability. A prototype of the proposed FSS is fabricated and tested. The measured results are in good agreement with the simulated results.read more
