“…By considering the gain and position of the transmitting horn, a plane wave is created at the FSS array. The Rx halfpower beam-width should be smaller than the FSS size to limit the coupling between the two antennas [27]. As such a 204 × 204 mm 2 FSS aperture is suitable to receive the transmitted plane wave by the receiving horn.…”

A novel metallic multi-band frequency selective surface (FSS) is presented. The proposed FSS structure has operation bands from closely spaced to far from each other (wide range of band ratio) and has high selectivity at each operation band. The unit cell comprises four small square slots, each loaded with multiple stub resonators. The stubs are placed in each slot in such a way that the unit cell response to both TE and TM polarizations are the same. To miniaturize the unit cell and cover the lower frequency range, each stub resonator is terminated with a U-shaped section. The length of each stubs within the slot determine the resonant frequency of each passbands. The band ratio can be set from 1.09 (close to each other) up to 2.35 (far from each other). Single, dual, triple and quad band FSS structures are designed and simulated through HFSS software package. The fabricated dual-band unit cell shows that the proposed FSS structure can provide two close to each other bands, 9.8 and 10.9 GHz. Also, the measured results of a fabricated dual-band 17 x 17 FSS array show a relatively stable response to variations of incidence angle and polarization state.

“…FSSs typically consist of one or multiple layers composed of resonant elements arranged in periodic grids [5]. An approach to improve the angular stability is to add additional quarterwave (λ/4) dielectric slabs on the two sides of the FSS [5], [6]. However, such a solution leads to electrically thick structures and is not effective in rejecting higher-order harmonics.…”

A 5-layer frequency selective surface (FSS) composed of subwavelength elements, with large harmonic rejection bandwidth is presented. The FSS design is based on an equivalent circuit model, where the inter-layer interaction is only described with a single transmission line representing the fundamental Floquet wave. A prototype of the designed FSS is fabricated and the measured response exhibits good stability over a wide conical incidence range, up to 45 •. The FSS is combined with a wide-scanning connected array of dipoles to implement a phased array with integrated filtering properties. A dispersion analysis is performed to define the distance between the array and the FSS that avoids the propagation of surface waves between the combined structure, allowing to maximize the radiation efficiency. The performance of the array combined with the FSS is experimentally characterized, showing high-order harmonic rejection better than 17 dB over a large bandwidth.

“…In the infrared and visible light wave regime of the spectrum, this kind of the structure is used as polarizer, beam splitter and in the solar energy collection, respectively [5,6]. In the microwave and millimeter wave regime of the electromagnetic structure, the application of this kind of the structure is also noticeable in the satellite communication where it is required to maintain the purity of the signal in the specific band and to control the transmission and reflection of the signal to the desired level [7,8].…”

Abstract-In this manuscript, a simple synthesis method of single square loop frequency selective surface (SSLFSS) is discussed, which may find the suitable application in the fast analysis and fabrication of the frequency-selective surface. The presented technique is used to design SSLFSS at 3 GHz, 15 GHz, 22 GHz and 26 GHz. At every frequency of interest, the analytical result is very close to the required result. Moreover, a way to control the reflection at any frequency is discussed, which may find an application in controlling the reflection level at any frequency. However, we have proposed two simple, cheaper and lightweight structures at 3 GHz and 22 GHz for the application in various satellite communications. The proposed process has been extended to the analysis of bandpass structure and desired results have been achieved, which indicates the utility of the method of synthesis of both the bandpass and bandstop structures.
