“…Fig. 7 shows the equivalent circuit of the 3-layer band-pass unit cell, similarly to [11]. Due to the symmetry of the unit cell (all layers are identical), only two different unit cells must be considered to account for the mutual coupling between layers, and between the external layers and the free-space region.…”

This paper presents a non-uniform frequency selective surface (FSS) working as a low-profile planar lens antenna. The FSS is designed using multilayer band-pass unit cells, in contrast to previously-designed planar lenses with multilayer metallic hole arrays. The advantage of the new unit cell resides in its smaller size compared to the metallic holes. These smaller cells provide a better control of the phase in the transmitted signal and, hence, a better performance in the complete planar structure. The fabrication of the new planar lens is straightforward since it just consists of several metallic layers, which facilitates the frequency scaling of the lens. This paper is focused on the behavior of the band-pass unit cell in front of the metallic holes, and presents a first design of a planar lens with band-pass unit cells.Index Terms-Frequency selective surfaces (FSS), planar lens, metallic hole-array, low-profile antennas.

“…Narrow, wide and ultrawideband nature of FSS fits them in diverse fields including radar cross section (RCS) reduction, electromagnetic shielding and antenna application. Single layer and dual layer FSS are reported in literature [5][6][7]. Simple circular slot FSS with active and passive components are capable of single or dual band operation [8], [9].…”

This paper presents a compact ultra-wideband frequency selective surface (FSS) with band stop response. The proposed single layer FSS is printed on FR-4 substrate with a unit cell periodicity of 0.138λ 0 × 0.138λ 0, corresponding to its lowest operating frequency. The developed FSS exhibits stable response for plane waves with normal and oblique incidence with TE and TM polarization for angles varying from 0° to 60°. The FSS offers -10dB bandwidth of 141 % covering the entire ultra-wideband frequency range from 2.39 GHz to 13.67 GHz. The structural parameters are optimized, and an equivalent circuit is modelled to analyze the performance of FSS. The simulated results are validated by the measured values.

“…Measurements exhibit that proposed FSS transmission curve is under -10 dB between 3.5 GHz and 11.45 GHz frequency range. In [13], a fourlayered UWB band stop FSS is presented. At each layer, the unit cell contains different length of square loop to obtain broad bandwidth from 10 GHz to 16.1 GHz.…”

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.
