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.

“…A stack of two FSS's printed on one-sided 0.76 mm Arlon Di 880 substrate, with square unit cell having 7.7 mm side size and incurved cross dipole metallization (for miniaturization of the straight dipole) is reported in [16]. The device features two notch frequencies in the X band that can be combined to create a frequency response with a large stopband, equivalent to an eighth-order filter.…”

Frequency Selective Surface With Two Quasi-Independent Notch Frequencies

A double-layer frequency selective surface (FSS) built on FR4 substrate exhibiting two notch frequencies in the 0-10-GHz range is introduced. Recently published examples demonstrate that further research needs to be undergone for obtaining separate tuning of the resulted notch frequencies. Thus, this issue is addressed in this paper: the notch frequencies can be quasi-independently set by appropriate values given to the geometrical parameters of the two metal patterns in the unit cells of the structure. The FSS behavior is stable with respect to the angle of incidence of impinging electromagnetic waves up to 45 • , as proved by simulation and validated by experiments. INDEX TERMS Frequency selective surface (FSS), notch filter, angular stability.

This study presents a novel Frequency Selective Surface (FSS) design with angularly stable and polarization independent band-stop response. The presented FSS comprises miniaturized unit cells printed on two layers of the dielectric substrates. The-3dB bandwidth of proposed FSS is between 2.98 GHz and 10.86 GHz frequencies. The unit cell dimension is 0.064λ  0.064λ with the thickness of 0.02λ, where λ is the wavelength of the lower operational frequency. The proposed FSS has angular stability up to 60 for TE polarization. The designed FSS is simulated and analyzed by using the commercial software, CST Microwave Studio. The simulation results are verified by measurements carried on a fabricated prototype and a good agreement is achieved.
