“…However, to the best of our knowledge, no operational full reflectarray with actual dynamic beam-scanning has been implemented so far, with the above examples demonstrating so-called 'frozen' MEMS array implementation for complexity reasons. The use of a micromotor for implementing the rotation has also been proposed and implemented in a unit cell [75], but not a full array configuration. …”

Abstract-Advances in reflectarrays and array lenses with electronic beam-forming capabilities are enabling a host of new possibilities for these high-performance, low-cost antenna architectures. This paper reviews enabling technologies and topologies of reconfigurable reflectarray and array lens designs, and surveys a range of experimental implementations and achievements that have been made in this area in recent years. The paper describes the fundamental design approaches employed in realizing reconfigurable designs, and explores advanced capabilities of these nascent architectures, such as multi-band operation, polarization manipulation, frequency agility, and amplification. Finally, the paper concludes by discussing future challenges and possibilities for these antennas.

“…The second one is the micro-electro-mechanical system (MEMS) assisted method. This method uses MEMS to adjust electromagnetic signals by controlling electromagnetic units, such as signal transmission delay change [27], electromagnetic units [28] rotation, and piezoelectric effect based capacitance change [29]. This kind of RIS has good linearity, low power consumption and high monolithic integration.…”

With the global commercialization of the fifth-generation (5G) network, many countries, including China, USA, European countries, Japan, and Korea, have started exploring 6G mobile communication network, following the tradition of "planning the next while commercializing one generation". Currently, studies on 6G networks are at the infancy stage. Research on the vision and requirements for 6G is still ongoing, and the industry is yet to clarify the key enabling technologies for 6G. However, 6G will certainly build on the success of 5G. Therefore, developing high-quality 5G networks and seamlessly integrating 5G with verticals are the priorities before 2030, when 6G is projected to be commercialized. Also, global 5G standards will keep evolving to better support vertical applications. As a milestone, the Third-Generation Partnership Project (3GPP) published Release 16 in July 2020, which continuously enhanced the capabilities of mobile broadband service based on Release 15 and realized the support for low-delay and high-reliability applications, such as Internet of Vehicles and industrial Internet. Currently, 3GPP is working on Releases 17 and 18, focusing on meeting the demands of medium-and high-data-rate machine communication with low-cost and high-precision positioning, which will be published in June 2022. Thus, 6G networks will further expand the application fields and scope of the Internet of Things to accommodate those services and applications that are beyond the capabilities of 5G networks. Herein, we present our vision, application scenarios, and key technological trends for 6G networks. Furthermore, we propose several future research opportunities in 6G networks with regard to industrialization and standardization.

A u g u s t 2 0 1 5 1045-9243/15©2015IEEE detailed overview of various design methodologies and enabling technologies for beam-scanning reflectarray antennas is presented in this article. Numerous advantages of reflectarrays over reflectors and phased arrays are delineated, and representative beam-scanning reflectarray antenna designs are reviewed. For limited field-of-view beam-scanning systems, utilizing the reflector nature of the reflectarray antenna and the feed-tuning technique can provide a simple solution with good performance. On the other hand, for applications where wideangle scan coverage is required, utilizing the array nature of the reflectarray and the aperture phase-tuning approach are the more suitable choices. There are various enabling technologies available for both design methodologies, making them a suitable choice for the new generation of high-speed, high-gain beam-scanning antennas. Microstrip reflectarraysSince the revolutionary breakthrough of printed antenna technology, microstrip reflectarrays have emerged as a new generation of high-gain antennas, combining many favorable features of both reflectors and printed arrays as well as offering an alternative design with low-profile and low-mass features [1], [2]. The aperture of a reflectarray antenna consists of elements arranged in a certain grid that are designed
