“…Figure 7(a) shows the S 21 curve of FSS when the arrangement angle α = 90 • , on this particular occasion, f p = 425.2 GHz, ∆P = −0.26 dB, grating lobe appears at around 558 GHz. But if the arrangement angle [23] changes to α = 60 • , the resonance point will be cut by 0.6 GHz (much closer to the required value 424 GHz), and the insertion loss will reduce from −0.26 dB to −0.19 dB, which means a better energy transmission capability. And the 3 dB pass band is also widen when comparing the two inner figures of Figures 7(a) and (b).…”

Abstract-The design of an efficient quasi-optics Frequency Selective Surface (FSS) filter which is required to provide a −3 dB pass band from 405 GHz to 441 GHz is presented. For atmospheric remote sensing application, this space-borne spatial device consists of a silicon layer and a thin copper layer which is perforated with periodic arrays of resonant dipole slots and circular apertures. FSS unit cell has a dimension much smaller than its operating wavelength. Unique features of this complex dense FSS structure include wide pass band properties with superb performance of frequency response and incident angles independence for TE polarization. Floquet mode analysis and finite element method (FEM) models are used to establish the geometry of the periodic structure and predict its spectral response.

“…For about 50 years, FSSs have been an attractive topic because of their comprehensive applications, such as filters, absorbers, polarizers, subreflectors, hybrid-radome for radar cross-section (RCS) controlling, etc. [3][4][5][6][7][8][9][10][11][12][13][14][15]. For decades, many novel FSS structures have been proposed to design FSSs with excellent performances.…”

Abstract-In this paper, a waveguide filter using miniaturizedelement frequency selective surface (FSS) is presented. The proposed FSS is composed of periodic array of metallic patches separated by small gaps and metallic lines. The array of patches constitutes a capacitive surface and the lines a coupled inductive surface, which together act as a resonant structure. At about 5.0 GHz, a narrow bandpass response is designed. Dimensions of the FSS element are much smaller than the operating wavelength, which is less than 1/13λ. For this miniaturized element, grating lobes are restrained and do not appear event to 25 GHz. Moreover, the FSS has stable performances for various incident angles. Design procedure and measurement results of the FSS are presented and discussed.

“…The FSS structure has a phenomenon with high impedance surface that reflects the plane wave in-phase and suppresses surface wave thus improving the radiation efficiency, bandwidth, and gain, and reducing the side and back lobe levels in its radiation pattern. For more than four decades the FSS has applications in the areas of filter [8][9][10][11][12][13], reflectors, absorbers [14][15][16], polarizers [17], planar metamaterials [18], and artificial magnetic conductors [19][20][21].…”

This paper proposes a new generation of antenna that applies metamaterial as a base construction. With the use of dual band high impedance surface (HIS) structures, the bandwidth, return loss, and gain of U-slot patch antenna is improved at resonant frequencies 2.24 GHz and 5.8 GHz.The proposed new modified U-slot antenna has dual band impedance bandwidth from about 2.1886 to 2.27 GHz and 5.6149 to 7.2259 GHz. From the simulation result it was found that the upper frequency band of the proposed antenna lies in the band of 5.725∼5.825 GHz regulated by IEEE 802.11a (upper band) and can be used for bluetooth and WLAN applications. We perform this analysis on structures which composed of rectangular lattice patches periodic arrangements. All the dimensions and shapes of the unit cell geometry are optimized in order to get a broad bandwidth and high return loss. The lattice structure comprises of an array of 7×5 rectangular patches embedded in the substrate.
