“…However, the proposed designs in [3], [4], [7] demonstrated smooth rather than sharp roll-offs, which also results in deteriorated out-ofband responses. Moreover, those proposed in [4]- [6] exhibit relatively poor out-of-band responses with high insertion loss values while featuring sharp roll-offs.…”

A novel three-dimensional frequency-selective structure with an ultra-wide bandstop response is proposed using a cascaded configuration of a two-dimensional array of vertically stacked parallel strip lines. The structure is designed to achieve a combined rejection response of two independently designed parallel strips etched on the same substrate material. The bandwidth and the position of the rejection band are configurable by controlling the lengths of the two cascaded parallel strips. An example design is presented with its measured result, achieving a -10 dB fractional bandwidth of 100%. The structure demonstrates a stable angular response under fairly large oblique incident angles given the wide bandwidth. The operating principles and design procedures are briefly explained.Index Terms -bandstop, frequency selective structure, parallel strip line, three-dimensional, wideband.

“…Wideband bandpass frequency selective surfaces (FSS) have been extensively reported in the literature while fewer wideband bandstop FSSs were proposed [3]- [7]. However, the proposed designs in [3], [4], [7] demonstrated smooth rather than sharp roll-offs, which also results in deteriorated out-ofband responses.…”

“…In recent years, frequency selective surfaces have become an interesting subject for many researchers. Frequency selective surfaces can be utilized to filter some specific frequencies in civil or military applications aiming to improve the front-to-back ratio of the antennas, reduce the out-of-band RCS of the antennas, shield the electromagnetic wave and suppress the interference from other communication systems [3][4][5][6][7][8][9][10][11]. It is difficult to design band-stop FSS with ultra-wideband angularly stable and sharp roll-off transition filtering response.…”

A novel compact band-stop frequency selective surface (FSS) with angular and polarization stability performance for ultra-wide band (UWB) applications is presented in this paper. The designed unit cell consists of a square loop element and a crossed dipole with a ring slot element. The novel unit cell size is miniaturized to 0.047λ × 0.047λ, where λ is free-space wavelength corresponding to the lowest frequency of the UWB band. The -3dB bandwidth of the proposed FSS is between 3.05 GHz and 10.73 GHz frequencies which covers the whole UWB band as defined by FCC. Due to compact size of unit cell, the proposed FSS has good angular stability up to 60° incident angles both perpendicular (TE) and parallel (TM) polarization. The maximum resonance frequency deviation is 1.75% for TE polarization. In addition, the proposed FSS has excellent stable resonant frequency. The designed FSS is fabricated and experimental measurements are performed. There is a good consistency between numerical simulations and measurement results.

“…For more than four decades, FSSs have been attractive because of their comprehensive applications, such as subreflectors, polarizers, fliters, band-pass hybrid radomes [1][2][3]. Compared with conventional filters, frequency responses of FSSs are dependent not only on frequency but also on incident angle and polarizations of incident electromagnetic waves.…”

Abstract-In this paper, we propose a novel frequency selective surface (FSS) with stable performance under large incident angles. The FSS is composed of hexagon metallic lines and hexagon patches. Using such a hexagon arrangement, the periodicity size could be miniaturized and thus the FSS unit cell is compact. The composite FSS has an excellent stability under large incident angles. In the passband 10.58-11.06 GHz, the insertion loss is still less than −1 dB for both TE and TM polarizations, even under incident angle up to 85 degree. Both the design procedure and experimental results of the novel FSS are presented and discussed.
