“…Spatial filters, also referred to as frequency selective surfaces (FSSs), are among the widely adopted and useful technique that can overcome EMI. FSSs are one‐ or two‐dimensional (1D or 2D) periodic arrays of identical metallic elements either printed on a dielectric substrate [1–15] or milled into a metallic surface. The FSS selectively rejects the undesired frequencies while acting transparent for the rest of the spectrum.…”

“…They behave as stopband or passband filters when illuminated by an EM wave. The corresponding spectral response depends upon the size and geometry of a unit cell, angle of incidence, substrate in use, and polarisation of incident wave [7]. However, when these filters are applied in a confined space, the large footprint of a unit cell comparable to the half wavelength (

λ / 2

) still remains a key challenge.…”

“…Dual stopband characteristics can be achieved by using anchor-shaped loop FSS structure [14], four small square slots loaded with multiple stub resonators [15] with higher design complexity, circular loop type FSS [16], square ring and four stubs loaded dual substrate FSS [17] for GSM and LTE, and double layer FSS [18] on glass substrate to protect WLAN bands 2.4-2.5 GHz and 4.98-5.825 GHz. Triple band-stop characteristics has been achieved using simple conducting elements on both sides [19], and here the design is simple and easily optimizable, but the angular stability is only up to 30 • .…”

Here, a multi-stopband frequency selective surface (FSS), covering commercial frequency bands CDMA, GSM-900, GSM-1800, LTE-2200 MHz, Wi-Fi, and Bluetooth for mobile communication applications has been proposed employing a pair of concentric square ring patches as a unit cell. Possibilities of annular ring patch type FSS are explored first. Finally, the design comes up with a compact square ring patch type single layer FSS. It is also explored that by increasing the width of the inner ring, operating bandwidth can be enhanced to cover closely spaced commercial frequency bands in a single band. Thereby the mutual coupling between the closely spaced resonators for multiple bands can be minimized. The proposed design is flexible enough to tune the desired resonance frequency by changing the length of the individual ring resonators. The design concept has been formulated using linear polynomial regression (LPR) techniques and validated through proper measurement of the fabricated prototype. This FSS can be used as a mobile back cover to protect mobile users from harmful radiations.

“…Frequency selective surface (FSS) can be defined as the periodic arrangement of metallic patches on dielectric substrate or that of slots on metal sheet . In different technologies in communication system such as radar, aircraft, satellite, and so forth, and household purposes, the filtering properties of FSS is used abundantly having simultaneous dual filtering characteristics (band pass and band stop) along with stable response at different incident and polarization angles of plane wave.…”

Miniaturized FSS is very useful in communication system. It is obtained by lowering the resonant frequency. Many good research works are reported on compact planar FSS, but it is challenging to decrease the resonant frequency in case of curved FSS. This article deals with the design and fabrication of compact patch type curved FSSs. Here maximum 50.31% compactness is achieved in semicylindrical curved FSS with square slit. Also the parametric studies have been analyzed by introducing same slit in circular and hexagonal patch elements of the curved FSSs. The proposed design has been fabricated. Simulated result has been ratified with experiment result.
