In this paper, we propose a new miniaturized dual band frequency selective surface (FSS) for Wi-Fi applications. The proposed FSS possesses 0.42 GHz and 0.30 GHz bandwidths with insertion loss less than −15 dB around the two central operating frequencies 2.4 GHz and 4.6 GHz, respectively. The FSS exhibits excellent miniaturization with 0.057⋋1 × 0.057⋋1 or 0.11⋋2×0.11⋋2 unit cells, where ⋋1 and ⋋2...
In this study, a closely-spaced, dual-band, band-pass frequency selective surface (FSS) is presented by cascading a two-layer periodic array. The proposed FSS provides two compact pass-bands separated by two transmission zeros, leading to highly selective response. Each pass-band contains two transmission poles, which results in a broad band performance. In addition, the FSS has wide out-of-band rejection...
In this paper, a miniaturized frequency selective surface (FSS) composed of convoluted element of dipoles is proposed. The FSS is printed on one face of a single-layer substrate with a relative permittivity of 2.65. The novel FSS has promising miniaturization characteristics with the unit cell dimension 0.042λ×0.042λ, where λ represents the free-space wavelength corresponding to the resonant frequency...
