“…Frequency selective surfaces, FSS, have attracted the attention of several research groups, both for simplicity of manufacture and for the diversity of applications [1]- [3]. Dual band antennas systems [4], [5], radomes [6], [7], electromagnetically smart buildings [8]- [10] and reconfigurable antennas [3], [11]- [13] are examples of FSS applications. Basically, a FSS is composed by a periodic array of unit cells, usually engraved on a dielectric substrate, designed to be transparent in some frequency bands, while reflecting or absorbing the others.…”

In reconfigurable frequency selective surface, FSS, bias lines can suppress a resonant frequency. This is a disadvantage, as it reduces a FSS potential application. In this paper, a procedure to recover the suppressed resonant frequency is described. A FSS based on four arms star geometry is considered and its reconfigurability is achieved by the use of varactors, for which bias lines suppress the polarization resonance. So, dipoles are added to the unit cell geometry recovering this resonance. In order to validate the proposed procedure, a reconfigurable FSS using the varactor SMV1231 ( . ≤ ≤ .) was fabricated and characterized. Numerical and measured results shown a good agreement, confirming that the FSS reconfigurability is preserved and the suppressed resonance recovered.

“…Nowadays, with the rapid development of electronic equipment, various beam-sweeping antennas have been developed. 1,2 Beam-sweeping antennas could reduce the influence of multipath fading while improving the flexibility of communication systems. The phased-array technique is widely employed in conventional beamsweeping antenna designs; however, this method may result in a large-size structure.…”

In this work, a simple and compact reconfigurable antenna, whose radiation direction and beamwidth can be manipulated, is proposed based on active frequency-selective surfaces (AFSSs). This design is completed by using a monopole antenna and six reflective AFSS screens, while its reconfigurable behavior is obtained by employing semiconductor switches. By applying different biasing voltages on the diode switches, the operating state of the AFSS screens can be configurated; therefore, the radiation direction and beamwidth of the monopole antenna can be controlled. From 1.8 to 2 GHz, the omnidirectional scanning response can be achieved at xoy-plane with the step of 60 and the maximum radiant efficiency is 96%. Furthermore, the 3 dB beamwidth can also be adjusted from 176 to 120 with the measured gains of 4.58-6.53 dB.The diameter of this structure is only 50 mm, which is a relatively small structural size for an omnidirectional beam-sweeping antenna. Finally, the proposed design is validated by numerical simulations and experimental measurements.

“…This will add a new entity to the network architecture which can be used to impart some level of control over the radio propagation environment and can also be used to establish a link between the BS and UE where an adequately strong link or line of sight (LOS) path does not exist. Another dynamic entity that has the potential of assisting mmWave communications is a Frequency Selective Surface (FSS) [6] that can be deployed instead of conventional walls or windows. These surfaces could be designed in such a way that they can interact with or pass the mmWave signals rather than attenuating them.…”

This paper presents a fully-transparent and novel frequency selective surface (FSS) that can be deployed instead of conventional glass to reduce the penetration loss encountered by millimeter wave (mmWave) frequencies in typical outdoorindoor (O2I) communication scenarios. The presented design uses a 0.035 mm thick layer of indium tin oxide (ITO), which is a transparent conducting oxide (TCO) deposited on the surface of the glass, thereby ensuring the transparency of the structure. The paper also presents a novel unit cell that has been used to design the hexagonal lattice of the FSS structure. The dispersion and transmission characteristics of the proposed design are presented and compared with conventional glass. The presented FSS can be used for both 26 GHz and 28 GHz bands of the mmWave spectrum and offers a lower transmission loss as compared to conventional glass without any considerable impact on the aesthetics of the building infrastructure. Index Terms-mmWave, transmission surface, frequency selective surface (FSS), transparent conductor (TC), indium tin oxide (ITO).
