Jan 29, 2019 · A wideband absorber with a good absorption performance is served as a matching load for multiband bandpass frequency selective surface (FSS) filters. As a result, the reflection coefficients of the proposed absorbers are in high accordance with the counterparts of the original bandpass FSS filters.

Apr 24, 2024 · This work presents a novel tri-band bandpass frequency selective surface (FSS) that achieves high-order filtering responses in different frequency bands by means of a complementary...

The triple band FSS exhibits stop bands near 2.4 GHz, 4.8 GHz, 8.8 GHz with adequate -10 dB bandwidths of 0.31 GHz, 0.55 GHz and 1.14 GHz respectively. Such response makes the FSS suitable for ISM band, C band X band applications.

A novel, compact, low-profile triple band FSS unit cell is introduced, and the working mechanism is described. By applying ANN based design procedure, the unit cell dimensions to resonate at the 5G mm-wave frequency band is extracted.

Feb 29, 2016 · A highly selective tri-band bandpass frequency-selective surface (FSS) is presented by cascading three layers of periodic arrays. The middle layer is composed of double square loops (DSLs) while the two exterior layers are composed of gridded-double square loops (G-DSLs) structure.

Jun 2, 2023 · 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.
