“…Finally, Figure 3(c) shows a possible equivalent circuit of a reflectarray element, which differs from that shown in (b) because the elements in a traditional reflectarray are typically comparable to a wavelength. Therefore, owing to the distributed nature of the scatterer, more sophisticated circuits are needed to represent the reactance block X shown in the figure [57], or even other circuit models entirely [36] [67]. Impedance surfaces can be easily adapted to have a tunable reflection phase.…”

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.

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

“…These considerations lead to the following three main conclusions: First, the characterization of a single reconfigurable cell placed in a conventional RWG is not sufficient to assess the performance of the cell because the array lattice thereby characterized does not, in general, correspond to a reflectarray free of grating lobes. Second, since the RWG only allows the characterization of incidence angles , it cannot be considered, in contrast with the statements of [29] and [30], as a fairly good approximation of the reflection phase for other pairs of frequency and angle, and especially for normal incidence . This remark holds for all planar elements, but was illustrated here in Fig.…”

Abstract-This paper presents new contributions to the modeling and design of reflecting cells embedding discrete control elements such as microelectromechanical system (MEMS) or diodes. First, a rigorous assessment of the different possibilities to simulate and measure the reconfigurable cell in a periodic environment is proposed. Strategies to efficiently model a cell comprising discrete control elements are then presented and discussed in terms of versatility, required assumptions, and computational effort. The most efficient method allows computing all reconfigurable states cell parameters, including information such as the total and dissipated power in each MEMS or diode, in a few minutes using a commercial full-wave solver and adequate post-processing. Finally, the benefit of such an efficient modeling is illustrated by the optimization of an element phase states distribution using a particle swarm optimizer. The concepts presented are also directly applicable to reconfigurable transmitting cells.
