“…In particular, great interest has been shown in the coplanar waveguide (CPW) due to its many features, such as its simplest structure consisting of a single metallic layer, lower surface wave loss, and smaller occupation, and its easy integration with an active device or microwave monolithic integrated circuit (MMICs). To come up with multiband and wide-band WLAN/WiMAX antennas, CPW-fed monopole antennas for multiband operation have been reported [3][4][5][6][7][8][9][10][11][12][13][14].…”

In this article, the authors propose the use of conducting patches with slots to design frequency selective surfaces (FSS) with dual bandstop for wireless LAN (WLAN) applications. The simulated results were obtained with the computer program Ansoft Designer TM . A prototype of the designed FSS was built and its transmission characteristics were measured. Excellent agreement between simulated and measured results was obtained. The FSS was useful for rejecting signals from industrial, scientific, and medical and unlicensed national information infrastructure bands and it presented angular stability.

The proposed antenna is simply composed of three arc-shaped strips and is capable of generating three separate resonant modes with good impedance matching conditions. The effects of varying the dimension on the proposed antenna performance were also studied. Prototypes of the proposed antenna were constructed and experimentally studied. The experiment results show that the proposed antenna covers 1.66-2.71, 2.95-4.54, and 5.02-6.10 GHz with 210 dB return loss, covering all the 2.4/5.5/5.8 WLAN bands and 2.5/3.5/5.5 GHz bands. Furthermore, this CPW-fed monopole antenna exhibits a nearly omnidirectional radiation pattern in the H-plane and a dipole-like radiation pattern in the E-plane. Also, good antenna gains for operating bands were obtained. V C 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:268-273, 2015; View this article online at wileyonlinelibrary.com.

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.

“…Various techniques for the design of multi-band and UWB FSSs were proposed in the literature, [1][2][3][4][5][6][7][8][9][10][11][12], such as dual-band structures based on stacked FSSs [4], multi-resonant elements [5] or single-layer FSS structure with multi-periodic elements [6][7]. A number of solutions aiming at the enhancement of bandwidth have also been proposed: In [8], garland like design printed on either side of the dielectric substrate shows angular and polarization independency.…”

“…By combining a number of narrow-band multi-band FSSs, a multi-layered FSS with a very wide stop band has been proposed [11] to achieve fractional bandwidth of 132%. This illustrates the large interest that exists in the field of design of FSSs with wideband response.…”

In this paper, novel frequency selective surfaces (FSS) with ultra-wideband (UWB) absorption are proposed, as well as a simple circuit model which can be used for their design. Multilayered unit cell is realized using square ring resonators and various parameters and their effect on the FSS transmission performances have been analysed. In order to demonstrate the applicability of the proposed unit cell in the design of UWB FSS, two examples are proposed, one FSS that operates at 13.9 GHz and consists of 3 layers, and another one: a 4-layered FSS that operates at 13.3 GHz. Simulation results show that the proposed surfaces exhibit highly selective stop bands with fractional bandwidths of more than 52%, in the case of normal incidence.
