“…Switches in the form of PIN diodes and micro-electrical-mechanical systems (MEMS) have been integrated with patches to control the current path and corresponding resonator length [40][59] [60]. Such methods depend on modelling techniques that allow for the analysis of the effect of tunable lumped element devices on the large scale electrical scattering characteristics of the device [48] [61]. In addition to using lumped element devices to effect changes in resonator lengths, more exotic techniques have also been contemplated, such as photo-induced plasmas for changing the length of slots coupled to reflectarray elements [32].…”

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.
