“…Also, the compactness is achieved by using both sides of the laminate. 19 Similarly, in another work, 20 a penta-bandstop metamaterial absorber is presented. The proposed singlelayer absorber offers five distinct absorption peaks for transverse electric (TE) incident wave while a single absorption peak is achieved for TM polarized incident wave.…”

This article reports on a single layer penta-bandstop frequency selective surface (FSS) for multiband shielding applications. The proposed unit cell incorporates five independent resonant elements that are realized on a single-sided FR4 substrate to suppress GSM-0.9 GHz, GPS-1.5 GHz, GSM-1.8 GHz, Wi-Max-3.5 GHz, and Wireless Local Area Network (WLAN)-5.7 GHz frequency bands. The proposed single layer unit cell has compact lattice periodicity of order 0.11 λ o × 0.11 λ o. The design is not only polarization-insensitive, but it also offers high angular stability up to 45. A detailed parametric analysis is conducted to establish a relationship between geometrical parameters and FSS spectral response. Additionally, an equivalent lumped circuit model is also derived to further elaborate on the underlying resonance mechanism. A prototype is fabricated and tested to validate the performance of the proposed FSS. The measured results are in good agreement with simulated ones. The proposed FSS has the uniqueness of suppressing 0.9 GHz GSM band that has never been reported in a pentaband design. The proposed FSS is a potential candidate for radio frequency (RF) shielding, electromagnetic wave suppression, and data security applications in secure installations.

“…This leads to enhancement of the transmission pass band in between these stop bands. 29 Figure 5 illustrates the surface current distribution of the proposed design when excited by a normal incident wave at 3.92, 5.68, and 7.92 GHz, under TE and TM polarizations. For simplicity, the current paths of individual elements at their respective resonant frequencies are illustrated, which explains the resonance mechanism of the proposed FSS unit cell design.…”

The design of a compact triple band notched Frequency Selective surface (FSS) at Ultra-Wide-Band (UWB) frequency range is presented. To make the proposed FSS polarization insensitive, on the upper part of the substrate a single metallic square loop (SL) and four identical rotational symmetric square split ring resonators (SSRR 1 ) are placed, whereas at the bottom part another four identical rotational symmetric SSRR loops (SSRR 2 ) are printed. Here each SSRR is rotated in 90 clockwise direction over a single layered FR4 substrate.Triple band notches are obtained at WiMAX and Satellite communication downlink C-band (3.3-4.2 GHz), WLAN (5.1-5.9 GHz) and Satellite communication X-band (7.2-8.4 GHz) for both TE and TM polarizations. Angular stability is achieved until 70 and attenuation of more than 25 dB is observed at resonance. The passband is obtained at 4.37 and 6.22 GHz. The proposed structure separates the closely spaced frequency bands by a ratio of 1.44 and 1.39 at the stop band and 1.42 at the pass band. The dimensions of the proposed FSS unit cell are 0.13λ 0 × 0.13λ 0 × 0.020 λ 0 , where λ 0 represents the free space wavelength at the lowest resonance frequency. Good agreement between modeled and measured results is obtained.

“…Next, a penta-bandstop FSS is obtained using different shapes of modified squared rings [28]. Later, a two-layer penta-bandstop FSS using five metallic structures, -two at one side of the dielectric and three on its other side-, was reported in [29]. More recently, a five stopband FSS, described in [30], is obtained by means of combining different loop geometries such as circles and squares in the unit cell.…”

This paper presents a polarization insensitive frequency selective surface (FSS) based on concentric ring slots with five closely spaced passbands. The proposed FSS unit cell contains five ring slots coupled with a supplementary innermost ring slot. The close band response within the first five transmission bands is achieved by the influence of the modified geometry obtained with the inclusion of the sixth ring slot. This added ring slot causes the appearance of a stopband, due to the conductive ring between the fifth and the sixth ring apertures, and a passband produced inherently by the sixth ring aperture. The effect of the additional stopband and passband in the FSS response has been investigated in the paper. Fullwave simulations reveal that a modified geometry with proper sizes effectively enables the close band response of the pentaband FSS. To validate the proposed approach, a 729-element penta-bandpass FSS prototype operating at millimeter-wave frequencies has been designed, fabricated, and tested. Experimental results in a free-space measurement setup indicate resonances at f1 = 26.7, f2 = 29.8, f3 = 33.6, f4 = 38.1, and f5 = 44.2 GHz, with resonant frequency ratios of f2/f1 = 1.12, f3/f2 = 1.13, f4/f3 = 1.13, and f5/f4 = 1.16. This FSS demonstrates an extremely low ratio of the highest and the lowest resonant frequencies (f5/f1 = 1.66) for a penta-band operation. This polarization insensitive FSS demonstrates good performance at oblique angular incidence for elevation angles up to 45°.
