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.

“…To enhance the gain or directivity of antennas, in recent years, the periodical structures in form of frequency selective surface (FSS) or artificial magnetic conductor (AMC) have been widely used [17][18][19][20][21][22][23][24][25][26][27]. Since the FSS and AMCs may possess extraordinary transmission or reflection properties at a desired frequency, they are superior to the traditional perfect electric conductor (PEC) ground planes.…”

Here, a silicon‐substrate‐based four element antenna system is investigated by using a coplanar frequency selective surface (FSS) as a novel parallel reflector to improve radiation and transmission characteristics of the antennas. The four antennas are arranged around the square FSS, and one of the antennas is used as the transmitting element, while the other three as the receiving ones. It is found that, owing to the stopband filtering and the linearly changing reflection phase of the designed coplanar FSS, the gain and directivity of the transmitting antenna have been greatly improved, and that the antenna system transmission coefficients, including S21, S31 and S41, have been significantly increased. Two types of the antenna systems have been designed and fabricated on a P‐type silicon wafer substrate for the cases with and without a coplanar FSS reflector. The measured S‐parameters are essentially consistent with those simulated. In comparison with the case without the FSS, the transmission coefficients of S21, S31 and S41 for the system with the FSS have been increased about 6.42, 5.97 and 5.89 dB at the center frequency of 5.42 GHz, respectively. Furthermore, the proposed coplanar FSS exhibits distinct advantage of low‐profile compared to the conventional vertical FSS reflector.

“…9 The multi-band FSSs with independent transmission bands are required in many applications such as satellite communication systems. There are different techniques to design multi band FSSs such as genetic algorithms 10,11 fractal elements, 12 multi-element unit cells, 13,14 non-resonant elements, 15 and using complementary structures. 16,17 In recent years, tunable FSSs have been considered and developed in multifunctional and multi-standard communication systems, multiband reflector antennas, and variable transmission windows in radomes.…”

In this paper, a dual polarized, dual band, low profile, embedded bias network, and compact tunable varactor band pass frequency selective surface (FSS) is designed with a wide tuning range. The proposed FSS is composed of two metallic layers printed on both sides of the substrate, where the top side has two cross strips with different dimensions encircled with high pass grids, whereas the bottom side includes a proper bias network. The loaded varactors between the grids and the cross strips with a designed bias network achieve two independent tunable pass bands. Moreover, an equivalent circuit of the FSS is extracted, which show good agreement with the full wave simulation results. The proposed FSS can operate from 2.28 GHz to 4.66 GHz and from 5.44 GHz to 11.3 GHz by proper tuning of the varactors loaded in the large and small cross strips. The tunable range of the low and high pass bands are about 70% with respect to the center frequency of each pass band. The electrical dimensions of the proposed FSS are about 0.05k Â 0.05k, where k is the free space wavelength at a lower pass band (2.28 GHz). Moreover, the proposed FSS works properly up to 60 incident angles. Published by AIP Publishing. https://doi.
