Abstract

In this paper, a flexible bandstop frequency selective surface (FSS) array fabricated on jeans substrate using silver-coated conductive yarn with a computerized embroidery machine is presented for X-band. The S parameters of the fabricated design are measured through the free space method. The measured S-parameters showed significant stopband characteristics between 8 GHz and 11.5 GHz for -30 degrees-30 degrees wide incident angles. Moreover, the transmission, reflection, absorption, and shielding effectiveness (SE) of the FSS array are also computed using measured S parameters. The prototype provides SE of more than 30 dB in X-band and has dominant absorption behavior for some frequencies within the band.
