Large deployable space mechanisms are widely used in the field of aerospace and have been paid increasingly high attention recently. The satellite antenna expansion system is the classic large deployable space mechanism. However, during the expansion of the satellite antenna deployable mechanism, the expansion accuracy is affected by the existing various uncertain factors which even result in scraping the satellite. For example, the hinge locking error has the significant influence on the deployment accuracy of the satellite antenna panel. In term of this issue, considering the advantage of the back‐propagation (BP) neural network for the high dimensional nonlinear problem, this paper mainly adopts it to analyze the impact of hinge locking error on the expansion accuracy of the antenna panel. The results show that the probability of the actual flatness deviation of the satellite antenna panel falling in the required accuracy area is 99.56%, and the probability of the actual pointing angle deviation falling in the required accuracy area is 99.84%.

“…By wire-control, it means that conducting wires are used to transmit control signals to tunable components or materials for reconfiguring the distribution of aperture fields. Three methods are typically used for designing reconfigurable microstrip RAs, where the electrical method is mostly adopted [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], compared to the mechanical method [23], [24], [25], [26] and optical method recently proposed [27], [28], [29]. For the electrical method, the key is to design the reconfigurable elements with tunable components or tunable materials, such as the positive-intrinsicnegative (p-i-n) diode switches [4], [5], [6], [7], [8], varactors [9], [10], [11], microelectromechanical (MEMS) switches [12], [13], [14], liquid crystals (LCs) [15], [16], [17], [18], phase-changing materials [19], ferroelectric materials [20], and graphene…”

In this article, the concept and design of light-controlled large-scale wirelessly reconfigurable microstrip reflectarrays are proposed. Unlike conventional electrically reconfigurable microstrip reflectarray antennas (RAs) that control the aperture phase distribution by conducting wires for transmitting control signals, the proposed method utilizes light to control the ON-and OFF-state of the integrated positive-intrinsic-negative (p-i-n) diodes wirelessly and binaurally through light-sensitive resistance of photodiodes (PDs). The concept is validated by simulation first, where a 1 bit 32 × 32 wirelessly reconfigurable microstrip RA is designed at 10 GHz with a beam-steering range of ±60 • for sidelobe levels <−10 dB, marking a record of 1024 elements with a tri-layer configuration. Experimentally, the light-control scheme is further validated by a smaller porotype of 256 elements, where a light-controlled beam steering from 30 • to 45 • is demonstrated. Compared with conventional wired reconfigurable microstrip RAs, the proposed method resolves the wire-routing complexity on the RA and offers a new possibility for further improving the maximum directivity, upper operating frequency, and the number of independently controllable polarizations of reconfigurable microstrip reflectarrays, paving the way for developing very-large reconfigurable intelligent surfaces (VRIS). Also, the proposed concept provides a new infrastructure for information exchange between light and microwaves.

“…One of the most popular types of mechanically reconfigurable antennas are those referred to as Origami Antennas (OA) as they take their inspiration from the Japanese art of paper folding. Origami antennas have been implemented in extensive ways, ranging from helical antennas capable of switching their radiating pattern polarization 11 , reducing system costs by utilizing paper as a substrate structure 12 , and frequency selective surfaces and deployable reflecting surfaces 13 , 14 . The biggest drawback of OAs is that specific behaviors and material performance assumptions need to be made in order to realize targeted functionality.…”

“…Lastly, when the incorporation of thin, flexible substrates (with signal or power traces) is used to replace traditional hinges in folded/deployable applications, upon creasing the substrate and traces, they experience deterioration of not only their mechanical integrity, but also their electrical performance, through material fatigue failure and cracking. These types of designs must still utilize additional supports to improve their structural integrity, which in turn increases their complexity and cost 11 , 12 , 14 , 19 . The limitations of thin and flexible substrates with minimal mechanical supporting structures can be seen in the real-world example of the Hubble telescope’s deployable boom and flat panel solar array structure experiencing jitter during orbital day-night crossings 20 .…”

Reconfigurable electromagnetic devices, specifically reconfigurable antennas, have shown to be integral to the future of communication systems. However, mechanically robust designs that can survive real-world, harsh environment applications and high-power conditions remain rare to this day. In this paper, the general framework for a field of both discrete and continuously mechanically reconfigurable devices is established by combining compliant mechanisms with electromagnetics. To exemplify this new concept, a reconfigurable compliant mechanism antenna is demonstrated which exhibits continuously tunable performance across a broad band of frequencies. Moreover, three additional examples are also introduced that further showcase the versatility and advanced capabilities of compliant mechanism enabled electromagnetic devices. Unlike previous approaches, this is achieved with minimal part counts, additive manufacturing techniques, and high reliability, which mechanical compliant mechanism devices are known for. The results presented exemplify how compliant mechanisms have the capacity to transform the broader field of reconfigurable electromagnetic devices.
