“…Zhou et al designed an array of thin metallic patches which exhibits zero index of refraction at 8.75GHz and consequently high directivity of 17.3dB was reported when two of these arrays were placed above a patch antenna [71]. In [72], a circular SRR-based superstrate enhanced the beam focusing of a microstrip antenna by 4dB while the bandwidth was also improved due to the presence of this metasurface. A flat lens in front of a horn antenna resulted in 2dB more gain and highly improved its aperture efficiency [73].…”

Metamaterials are artificial structures with the ability of exhibiting unusual and exotic electromagnetic properties such as the realisation of negative permittivity and permeability. Due to their unique characteristics, metamaterials have drawn broad interest and are considered to be a promising solution for improving the performance and overcoming the limitations of microwave components and especially antennas. This paper presents a detailed review of the most recent advancements associated with the design of metamaterial-based antennas. A brief introduction to the theory of metamaterials is provided in order to gain an insight into their working principle. Furthermore, the current state-of-theart regarding antenna miniaturisation, gain and isolation enhancement with metamaterials is investigated. Emphasis is primarily placed on practical metamaterial antenna applications that outperform conventional methods and are anticipated to play an active role in future wireless communications. The paper also presents and discusses various design challenges that demand further research and development efforts.

An Inclusive Survey on Array Antenna Design for Millimeter-Wave Communications

The enormous growth of wireless data traffic in recent years has made the millimeter-wave (mm-wave) technology as a good fit for high-speed communication systems. Extensive works are continuing from the device to system, to the radio architecture, to the network to support the communication in mm-wave frequency ranges. To support this extensive high data rate, beam forming is found to be the key-enabling technology. Hence, an array antenna design is an extremely important issue. The beam-forming arrays are chosen to achieve the desired link capacity considering the high path loss and atmospheric loss at mm-wave frequencies and also to increase the coverage of the mm-wave communication system. There are diverse design challenges of the array due to the small size, use of large numbers of antennas in close vicinity, integration with radio-frequency (RF) front ends, hardware constraints, and so on. This paper focuses on the evolution and development of mm-wave array antenna and its implementation for wireless communication and numerous other related areas. The scope of the discussion is extended on the reported works in every sphere of mm-wave antenna array design, including the selection of antenna elements, array configurations, feed mechanism, integration with front-end circuitry to understand the effects on system performance, and the underlying reason of it. The new design aspects and research directions are unfolded as a result of this discussion.INDEX TERMS Mm-wave communication, antenna array design, array configuration, feed mechanism, RF circuit.

This paper presents a Sunlight-Radio Frequency (RF) energy harvesting system built on Solar Panel Mesh Dipole Antenna integration. The dipole antenna mesh is mounted on the surface of the solar panel at the separations between the cells. This configuration maximizes the absorption of both solar and RF energies. Further, the multiple mesh antennas are integrated vertically to increase the RF harvested power. Each antenna output is connected to a six-stage RF-Voltage Doubler Rectifier (RF-VDR) circuit to convert the RF signal to a direct current (DC) and added to the solar panel DC output. This paper involves the design analysis of the antenna parameters, the integration process, and the design of the RF matching circuit. Prototype tests show that the proposed mesh dipole antenna has 83% efficiency. This is better than earlier similar designs published. From previous designs, the measured RF to DC conversion efficiency (CE) of the VDR circuit was merely 62% when the RF input equals -14 dBm. Moreover, the solar panel efficiency has been enhanced by 41.3 % when the input RF power density equals 49.16 mW/m 2 . Finally, the results proved that the proposed solar antenna system achieves 28.5 % power CE and outperforms the others that use transparent patch antennas.
