In this letter, a new triple‐band millimeter‐wave frequency selective surface (FSS) is presented. The proposed FSS structure consists of three slot‐based resonance mechanisms on the single layer of Rogers Diclad880 dielectric. It shows a high compactness with a unit cell surface area of 5.4 × 5.4 mm2. The proposed FSS exhibits a triple‐band bandpass filter characteristics for the allocated 5G millimeter‐wave frequency regions with sufficient bandwidths corresponding to 23.5–24.6, 27–28.5, and 37.5–41 GHz, respectively. Simulation outcomes reveal that the FSS poses polarization insensitive behavior, and maintains high transmission skill for a wide range of incident angles up to 40°. A 40 × 40 FSS panel is fabricated, and the experimental verification is carried out. The outcomes prove that the proposed FSS is suitable for multiband 5G millimeter‐wave filtering applications.

“…Therefore, polarization-and incident-angle-insensitive FSSs along with miniaturization characteristics have evinced significant research attention in recent years. Besides, extensive research is ongoing to miniaturize the FSS profile and improve the frequency response with broader bandwidth at higher incidence angles which are also capable of supporting, filtering, or converting different EM wave polarization [16][17][18][19][20] . It must be noted that the single layered FSSs though they are easy to fabricate and implement, however they are inefficient 21 both in terms of amplitude and phase response over frequency.…”

This article presents two transmissive metasurfaces coated on a glassy window to enhance the 5G outdoor to indoor (O2I) coverage inside vehicles and buildings. Two different wide-incident angle, and polarization insensitive unit cells are proposed for both single-glazing and double glazing glasses and have been arranged in a periodic structure to construct the transmission surfaces. Both metasurfaces are optically transparent as Indium Tin Oxide (ITO) is used as a conductive part of each unit cell. The proposed transmission surfaces empower the indoor coverage of 5G signals at 3.5 GHz band for wide range of incident angels. Although multi-layer structures are generally more sensitive to angle of incidence, however, both proposed two layered transmissive surfaces offer wide angular stability up to 65 and 75 degrees for double-and single-glazed glass accordingly. In order to achieve wide stable angular response, evolutionary optimization techniques have been used to optimise the proposed unit-cells. Both designs support high transmission coefficient over the operating frequency for wide incident angles which are higher than reported structures in the literature review. The fabricated prototypes have been evaluated experimentally and from measured results, it appears that both metasurfaces offer significant potential to improve propagation into buildings and vehicles.

“…1 Frequency-selective surfaces (FSSs) realized on daily surfaces are one of the key components for IoT applications that cater to manipulate and filter radio waves intelligently and they are paving the way for independent interaction between objects and their surroundings. [2][3][4][5][6][7][8][9][10] Hence, for fulfilling IoT potential, smart surfaces should provide multifunctional features. One of the features is seamless integration on aforesaid objects, which may comprise everyday materials, that can be used on walls, windows, and floors by providing low-cost and low-profile characteristics.…”

Optically transparent dual‐band frequency‐selective surfaces (FSSs) are promising candidates to address the specific design challenges of the Internet of Things. This paper demonstrates their potential by discussing different configurations of the two single‐layer FSS designs on an innovative optically transparent polyvinyl chloride surface material. First, FSS cells consist of two cross dipoles placed forming angles of , where each rotated dipole structure parallel to the other. Then, in the second design, each one of the two cells is mirrored to enable polarization control for each band. As a proof‐of‐concept, five prototypes of each design having a unit cell size of are fabricated through a combination of cost‐effective printing and shearing. The manufactured prototypes yield more than 93% transparency and robust dual‐band performance. Moreover, more than 20 and 40 dB isolation for lower‐ and upper‐frequency bands are achieved from the fabricated prototypes. High‐transparency, cost‐effectiveness, and robust high performance in terms of suppression make both structures suitable for sub‐6‐GHz fifth generation applications.
