“…Compared with the designs proposed in [6,8,16,27], the modified designs in this paper have a larger fractional bandwidth with clean transition bands by introducing knitted structures. Although the designs in [9,15] have larger fractional bandwidth than the proposed modified miniaturized FSSs, these 3-D FSSs operate under single polarization in their reports, which limits the practical applications of these FSSs. Compared with these previous single-polarized 3-D FSSs presented in Table 3, the proposed modified miniaturized FSSs are dual-polarized.…”

To extend the wideband performance of high-order band-pass filtering applications, optimized designs with knitted structures based on traditional miniaturized frequency-selective surfaces (FSSs) are proposed in this paper. The presented miniaturized FSSs consist of multiple metallic capacitive layers, knitted inductive layers, and substrates. In contrast to the conventional high-order miniaturized FSSs composed of metallic frames, patches, and substrates, the optimized miniaturized FSSs replace the original metallic wire frames with knitted structures. Both proposed modified miniaturized FSSs achieve a flat pass-band from 5.5 GHz to 10.3 GHz with a 3 dB bandwidth of 71.6% under vertical incidence. The unit cells have dimensions of 0.16 λ0 × 0.16 λ0 × 0.284 λ0 and 0.16 λ0 × 0.16 λ0 × 0.279 λ0, respectively, where λ0 is the free space wavelength at 7.9 GHz, which is the center frequency of the operating band. Numerical simulations and measurements demonstrate that the proposed modified miniaturized FSSs exhibit excellent wideband performance with clean transition bands around the pass-band during oblique incidence and are suitable for applications such as radomes, where wideband filtering is essential for covering multi-band functions of radar or communication instruments.

“…However, the structure of this 3-D FSS is complex and the parameters of the structure are hard to design. An ultrawideband threedimensional band-pass FSS was proposed by Shao and Zhang [9]. The unit cell of the proposed 3-D FSS consists of a wire-loop conducting pattern which is printed on a dielectric substrate.…”

“…In addition to offering the benefits of directed radiation, 3D FSS design can improve the directivity of antennas and significantly lower interference by boosting the component's height [27]. It is widely used in mobile communication, infrared sensing, and radar scattering cross section (RCS) [44][45][46] due to its outstanding roll-off performance and angular stability.…”

We propose a bandpass frequency selective surface (FSS) with fast cut-off characteristics and low insertion loss. It consists of a compact high-frequency hybrid compression board with five metal layers, two Rogers RO4003C layers, and two F4B layers. The hierarchical fitting of equivalent circuits is utilized to analyze the FSS, which maintains angular stability for dual-polarized electromagnetic waves at incidence angles of less than 20 degrees. Under normal incidence, transmission amplitudes in the K-band exceed −0.87 dB. Furthermore, the proposed FSS achieves a roll-off rate of 87.6 dB/GHz, which can be applied in dual-frequency observing systems for millimeter astronomy.
