“…The design of frequency selective surfaces (FSSs) has attracted an increased interest over the last years, thanks to their multiple applications in different communication systems. [1][2][3][4] Lightweight, low profile, and simple FSS structures are typically required for satellite communication applications, which can be obtained using multiresonant FSS elements. The property of stability under large incidence angles becomes an essential requirement.…”

A novel tri‐band frequency selective surface (FSS) is proposed for space antenna systems in the X, K, and Ka bands. The FSS structure is based on a two‐layer configuration, where the unit‐cell elements at each layer consist of two pairs of rectangular‐shaped dipoles and a square ring. The FSS has been designed to be transmissive at 11.5 GHz (X band) and totally reflective at 20 GHz (K band) and 30 GHz (Ka band). The reflection losses in K and Ka bands are less than 0.1 dB for incidence angles varying from 0° to 45°. Also, the transmission losses in X band are less than 0.5 dB for incidence angles of up to 30°. A 30‐cm prototype of the proposed two‐layer FSS has been fabricated and tested. Both simulation and measurement results show a good agreement and a satisfactory performance in the three operating bands.

“…In recent years, the FSS with simple shape and closely spaced multi-band resonance of miniaturized size and stable response becomes a research hotspot because of the increasing demands on multi-functionality of antennas and filters for both commercial and military applications [7,8]. Dual [9,10,11,12,13,14], triple [15,16,17] and wideband [18,19] FSSs can be used for communication filtering, absorbing or electromagnetic interference (EMI) shielding. However, few can be applied to the passband with wide stopband [20,21].…”

A novel compact multi-band frequency selective surface (FSS) with dual passbands and wide upper stopband is presented. The proposed FSS was originally a double-layer structure. The grid-double square loops (G-DSLs) are located at the bottom to achieve the dual passband characteristics. In order to realize wide upper stopband, a modified square ring and a Jerusalem cross (M-SR-JC) element structure at top and bottom are used. Considering the higher power engineering applications, the final FSS uses a multi-layer structure. The FSS provides two pass-bands centered at 3.8 and 5.8 GHz with relative bandwidths of 18.4% and 13.5%, respectively. It also provides wide stopband characteristics from 10.8 GHz to 14.5 GHz. The simulation and measurement are in good agreement. The novel FSS with dual passbands and wide upper stopband is compact; easy to design and fabricate, and achieves relatively stable multi-band response under different polarization states and different incident angles. The proposed FSS can better meet the engineering requirements.

“…New geometries such as convoluted ring slots, fractal, multipoles, and patches or their complementary structures have been proposed, where the size of unit cell was shrunk to [7], [8]. Miniaturized FSS was proposed comprising of a periodic array of a dual-concentric square element with reduced size slots printed on one side of a dielectric substrate, and an inductive grid printed on the other side [9]. The combination of the capacitance of the patch array and inductance of the wire mesh results in a parallel LC combination, which acts as a first-order bandpass filter at the resonant frequency of the structure.…”

A new type of Frequency Selective Surface (FSS) with miniaturized resonator element is proposed. The FSS structure is shown to have a FSS unit cell dimension that is miniaturized to 0.067 . Miniaturization of the FSS unit cell is achieved by coupling two meandered wire resonators separated by single thin substrate layer. The capacitance due to the small separation between the meandered wire elements results in a lowering of the resonant frequency. To demonstrate the validity of the design, the meandered wire resonator FSS was fabricated and tested using a free space measurement facility. The FSS produces a stable angular response up to 80 degrees for TE and TM incident angles.Index Terms-Angular stability, frequency selective surface, FSS, incident angle, meandered wire, miniature resonator.
