“…Furthermore, FSSs are used on the printed with conductive materials, or within the wall itself, by combining the isolation material with the added layer of printed or etched FSS pattern. Other proposals, such as use passive FSS designs applied as coatings on energy‐saving glass to selectively allow certain frequencies to pass through, while trying to minimize the impact on the shielding properties …”

In this work, a dual‐band frequency selective surface (FSS) is proposed to be placed perpendicularly into the apertures of horn antennas for prefiltering 900 and 1800 MHz GSM signals interfering during the signal reception, with the enhanced return loss, gain, and directivity at the desired frequencies. For this purpose, the microstrip double square loop MDSL is modified in the first stage. As for the second stage, an FSS array (2 × 2) is built up arranging the unit MDSLs in a periodic structure and finally these FSS unit arrays are fixed perpendicularly covering the aperture of a ridged horn antenna which is a part of the available radar system operating between 0.5 and 3 GHz in our laboratory, to construct an integrated module having both bandstop prefilter and horn antenna called “filtenna.” The simulated and experimental results are agreed that the proposed FSS structure attenuates GSM signals at the 900 and 1800 MHz through the high reflection and very poor transmission mechanisms meanwhile enhances return loss characteristics, radiation pattern, and gain of the horn antenna in the desired band. Thus, it can be concluded that these simple microstrip FSS structure can be effectively adapted to the horn antennas which need the GSM prefiltering.

“…This research not only has an important scientific significance, but also has an practical value in the field of radar absorbing material, communication window, fabric antenna, flexible functional clothing and so on [11,12]. At present, domestic and foreign researchers have studied 2D FSF by screen printing [13,14], weaving [15], weft knitting [16,17], embroidery [18,19], selective chemical plating [20], ink-jet printing [21] or other textile processing.…”

In this study, the three-dimension (3D) frequency selective fabrics (FSFs) fabricated by U-shaped velvet, using copper wires or silver filaments as the conductive unit material, were prepared. Specimens with different unit structure parameters were experimented and analyzed. Compared to FSFs with dipole unit structure, the velvet fabrics with the same unit length have two resonance peaks in the test frequency range. With an increase of inclination angle of velvet, the resonance frequency is changed slightly, accompanied by a trend of decreasing first and then stabilizing. And the resonance frequency of the FSF would shift slowly to higher frequency under the condition of increasing the linear density of conductive ply yarns. If the total length of U-shaped unit on the bottom is greater, the resonance frequency will go to the lower one. If the total length of U-shaped unit is same, specimens with the different number of unit will have the similar resonance frequencies. This work shows that the unit structure of U-shaped velvet FSFs can be designed with more parameters comparing with planar FSF.

This article presents the development of textile compact microstrip filters using jeans fabric dielectric substrates and pure copper polyester taffeta fabric conducting strips. Microstrip circuits such as antennas, filters, and frequency selective surfaces on textile materials exhibit some advantages over the traditional ones on microwave dielectric substrates, such as high flexibility, low weight, low cost, and easy fabrication. The proposed textile filter with inverted double‐E geometry is analyzed using the wave concept iterative procedure (WCIP), a full‐wave method, and through Ansoft Designer software. Filters with multiband reject performance are designed. For the purpose of validation, prototypes are manufactured and measured. Simulation (WCIP and Ansoft Designer) and measurement results are in excellent agreement. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:2543–2548, 2015
