Miniaturized Frequency Selective Surface for 6G Communication

Abstract

A single-layer, quartz-supported frequency selective surface (FSS) with a gear-shaped metallic array is proposed for 6G communication. Full-wave simulation, along with the method of equivalent circuit, is applied to investigate the transmission characteristics, while the distributions of surface current distribution, as well as electric field and magnetic fields, are studied to further interpret the transmission mechanism. The simulation indicates that the resonant frequency of 131 GHz with an attenuation of −40 dB can be obtained and the relative bandwidth approximates to 12%. The transmission response of the fabricated FSS prototype is measured using the free space measurement setup. The measured results show a good agreement with the simulated ones, which demonstrates the reliability of the design and fabrication. The proposed FSS with the advantages of simple structure, low cost, easy fabrication, and integration can be applied in enhancing the communication performance and anti-interference ability in the future 6G communication system.

Implementation of a second‐order frequency selective surface filter at mmWave using paper and silver ink

“…Frequency Selective Surfaces (FSS) are thin surfaces with a repeated pattern design that absorbs, reflects, or transmits a specific frequency [16]. Most reported FSS are made on rigid, flat, smooth surfaces, for example, metal patterning on glass [17,18] and rigid polymers [19], and direct patterned etching of printed circuit board (PCB) laminates [14,20]. In recent years, printing techniques such as screen printing [20], inkjet printing [20][21][22], lithographic techniques [20,21,23] and hot stamping [24] have all been used to print FSS on flexible yet smooth surfaces such as paper [25], special foil [24], plastic [22] or textile [20,26].…”

Miniaturized frequency‐selective surface with reduced number of metallic vias for electromagnetic shielding

“…The Ka ‐band miniaturized FSS in Chou and Ke 15 and the FSS for shielding 5G frequencies (2.6 GHz) reported in Qu et al 16 signify the importance of FSS for satellite communications and system‐level packaging, respectively. A few other interesting design solutions to obtain miniaturization in the FSS unit cells are described in other studies 17–22 …”

“…A few other interesting design solutions to obtain miniaturization in the FSS unit cells are described in other studies. [17][18][19][20][21][22] This paper reports the design of a novel ultra-miniaturized FSS with polarization-insensitive and angularly stable characteristics. The proposed FSS element has the smallest footprint of 0.026λ o  0.026λ o with a minimum via structures unlike the FSS screens reported in other studies.…”
