“…Different approaches have been used to develop FSS, from conventional designs based on resonators implemented over rigid substrates [9][10][11], FSS based on 3D printing [12], the use of high permittivity ceramic materials in order to avoid conductive materials [13], thicker multiband designs based on substrate integrated waveguide (SIW) technology [14] or multilayered designs [15]. The before mentioned alternatives present different advantages, such as the possibility of achieving high precision details in the fabricated prototypes.…”

A flexible fully textile-integrated bandstop frequency selective surface working at a central frequency of 3.75 GHz and presenting a 0.6 GHz bandwidth has been designed, manufactured and experimentally characterised. The frequency selective surface consists of a multilayered woven fabric whose top layer presents periodic cross-shaped conductive resonators, and due to its symmetries, its performance is largely independent of polarisation and angle of incidence. These properties make the prototype very interesting for shielding applications. The designed frequency selective surface is based on a layer-to-layer angle interlock 3D woven fabric. This technology provides the prototype with flexibility, portability and the possibility of manufacturing it in a large scale production by the use of existing industrial weaving machinery, in contrast to conventional frequency selective surfaces manufactured using rigid substrates. The proposed textile frequency selective surface has been simulated and experimentally validated providing good agreement between the simulations and measurements. The measured maximum attenuation has been found to be higher than 25 dB under normal incidence conditions.

“…However, although the numerical simulations yield accurate frequency response for a given FSS structure, they cannot provide adequate information on how to start an FSS design and how to initialize the geometrical sizes of the design to fulfill the expected frequency response of a general form. As a powerful analysis tool, the equivalent circuit method (ECM) is often utilized to reveal the operation principles of an FSS and to provide an approximate frequency response with acceptable accuracy to the designers [3][4][5], but we can rarely find the FSS designs that are implemented by using the ECM as a design tool according to the required frequency response [6].…”

“…In general, in order to realize a filter with an arbitrary desired frequency response, one usually needs four types of basic circuits that can provide the high-pass (HP), low-pass (LP), band-pass (BP), and band-stop (BS) filtering functionalities. Among many FSS designs [3][4][5][6][7][8][9], the FSSs consisting of the strip grid (SG), the square patch (SP), the square slot (SS), and the square loop (SL) elements present excellent HP, LP, BP, and BS performances, respectively, in terms of insensitivity to the polarization and angle of incidence. erefore, in principle, these four types of basic structures are good candidates which can be used to construct FSSs with more complicated and required properties.…”

An equivalent circuit method (ECM) is proposed for the design of multilayer frequency-selective surfaces (FSSs). In contrast to the existing ECMs that were developed mainly for the analysis of the properties of a given FSS, the presented ECM aims at providing the initial design parameters of an FSS from the desired frequency response. In this method, four types of basic FSS structures are used as the building blocks to construct the multilayer FSSs, and their surface impedances in both the normal-and the obliqueincidence situations are studied in detail in order to achieve more accurate equivalent circuit (EC) representation of the entire FSS. For a general FSS design with expected frequency response, the EC parameters and the geometrical sizes of the required basic building blocks can be synthesized from a few typical S-parameter (S 11 /S 12 ) samplings of the response curves via a simple leastsquare curve-fitting process. e effectiveness and accuracy of the method are shown by the designs of a band-pass FSS with steep falling edge and a miniaturized band-pass FSS with out-of-band absorption. e prototype of one design is fabricated, and the measured frequency response agrees well with the numerical results of the ECM and the full-wave simulations.

A broadband flexible fully textile-integrated bandstop frequency selective surface working at a central frequency of 5 GHz and presenting a 1.8 GHz bandwidth has been designed, manufactured and experimentally characterised. The frequency selective surface consists of two isolated layers of periodic square-shaped conductive rings and, due to its symmetries, its performance is largely independent of polarisation and angle of incidence. The textile frequency selective surface has been simulated and experimentally validated under bent conditions providing a stable performance.
