“…From the scalar nature of the metasurface follows that the TM and TE polarization of the field could be designed separately. This aspect has been used to design polarization-insensitive antennas [111], dual-circularly polarized antenna [112], polarization reconfigurable antennas [113] and to generate different beams using multiple sources [114].…”

In recent years, metasurfaces have become a rapidly growing domain of research in several fields of engineering and applied physics due to their ability to manipulate both phase and amplitude of electromagnetic fields. These artificial 2D-materials, usually composed of metallic elements printed on dielectric substrates, have the advantages of being low profile, lightweight as well as easy to fabricate and integrate with standard circuit technologies. In this context, this paper reviews the latest progress in metasurface antenna design, where metasurfaces are used to miniaturize the profile, increase the bandwidth, and control the radiation pattern in the near-and far-field regions.Résumé. Ces dernières années, la thématique des métasurfaces est devenue un sujet de recherche en pleine expansion dans plusieurs domaines de l'ingénierie et de la physique appliquée, en raison de leur capacité à manipuler à la fois la phase et l'amplitude des champs électromagnétiques. Ces matériaux artificiels bidimensionnels, généralement composés d'éléments métalliques imprimés sur des substrats diélectriques, ont l'avantage d'être de très faible épaisseur, légers et faciles à fabriquer et à intégrer avec les circuits imprimés. Cet article passe en revue les dernières avancées dans la conception d'antennes à métasurface, où les métasurfaces sont utilisées pour minimiser l'épaisseur, augmenter la bande passante et contrôler le diagramme de rayonnement en champ proche et en champ lointain.

“…The comparisons among the reported referenced antennas and the proposed polarization-reconfigurable holographic antenna are shown in Table 3. As is demonstrated in Table 3, holographic antennas are capable of obtaining the admirable high directivity performance, while their polarization diversity property is difficult to be electrically controlled [3], [7], [13], [14]. For array-type polarizationreconfigurable antennas, the number of PIN diodes are increased to obtain a higher directivity [24], [27].…”

“…Furthermore, in order to make the holographic antennas versatile to meet different application situations, multi-function holographic antennas have been studied. A dual band holographic antenna was designed in [10] and a dual CP holographic antenna was theoretically and experimentally analyzed in [13], [14]. A polarization-diversity holographic antenna, which could realize LP or CP radiation by controlling the magnitude and phase of four excitation ports, was reported in [15].…”

In this paper, the feasibility of utilizing the microwave hologram to realize the high-gain radiation with polarization agility performance is investigated, and an effective method to design the polarizationreconfigurable holographic antenna is presented. By utilizing a polarization-insensitive hologram as the leaky-wave radiating structure and an appropriately designed, embedded, polarization-reconfigurable feeding launcher to control the polarization state of the radiating leaky waves, a polarization-reconfigurable holographic antenna with broadside radiation and linearly polarized (LP), right-hand circularly polarized (RHCP), and left-hand circularly polarized (LHCP) polarization diversity is successfully achieved. The simulation results demonstrate that the proposed antenna exhibits pencil beams with aperture efficiency up to 28.3% for the three polarization states. Meanwhile, the stable gain performance with peak gain above 17.5 dBi and gain fluctuation less than 1.7 dB is obtained for the three reconfigurable polarization states. For verification, a prototype was fabricated and tested to validate the proposed design concept. Moreover, the working mechanism is investigated.

“…But these structures are typically heavy with high profile and require large source‐aperture separation. Metasurface (MTS) antennas have attracted substantial recent interest for various applications 8–13 such as synthetic aperture radar (SAR) and multiple‐input‐multiple‐output (MIMO) systems 14,15 and RF energy harvesting 16–18 . Metasurface is essentially a surface distribution of electrically small resonators, where the distance between adjacent resonators is electrically very small 19 .…”

A circularly polarized, high aperture efficiency antenna based on metasurface (MTS), inexpensively fabricated using a standard printed circuit board (PCB) technology, is presented. An array of 8 8 cross‐shaped resonators was designed to operate at 3.1 GHz with a 12 cm 12 cm (i.e., 1.24 1.24 ) footprint size. Each resonator was double fed (by two lines) with appropriate phases to achieve circular polarization. Full characterization of the designed antenna was achieved using full‐wave simulations. The MTS antenna was fabricated using a multilayer PCB technology and experimentally tested. A good agreement between the simulation results and measurements was observed. According to the measurements, with a realized gain of 11.1 dBi, the antenna has an aperture efficiency of 66.7%, which is high compared to many other antennas.
