“…The antenna is folded and unfolded with the help of an actuation system to the various heights from 60 mm to 145 mm. The actuation system is also employed in multi-radii monofilar helical antenna [73]. The antenna reconfigures between three bands of 1.22-1.84 GHz and 1.78-3.54 GHz and 3.64-4.04 GHz, with circular polarization.…”

Reconfigurable antennas have gained tremendous interest owing to their multifunctional capabilities while adhering to minimalistic space requirements in ever-shrinking electronics platforms and devices. A stark increase in demand for flexible and conformal antennas in modern and emerging unobtrusive and space-limited electronic systems has led to the development of the flexible and conformal reconfigurable antennas era. Flexible and conformal antennas rely on non-conventional materials and realization approaches, and thus, despite the mature knowledge available for rigid reconfigurable antennas, conventional reconfigurable techniques are not translated to a flexible domain in a straight forward manner. There are notable challenges associated with integration of reconfiguration elements such as switches, mechanical stability of the overall reconfigurable antenna, and the electronic robustness of the resulting devices when exposed to folding of sustained bending operations. This paper reviews various approaches demonstrated thus far, to realize flexible reconfigurable antennas, categorizing them on the basis of reconfiguration attributes, i.e., frequency, pattern, polarization, or a combination of these characteristics. The challenges associated with development and characterization of flexible and conformal reconfigurable antennas, the strengths and limitations of available methods are reviewed considering the progress in recent years, and open challenges for the future research are identified.

“…For multi-functional radars and communications antennas, achieving reconfiguration within the CubeSat form factor is challenging due to space limitations. Existing methods for physically reconfiguring antennas include origami folding [9], hinges [8], [10], spring forces [11], [12], soft robotics [13], and telescopic actuation [14]. However, these techniques may add significant mechanical complexity, making it difficult to scale.…”

The development of reconfigurable antennas compatible with a CubeSat form factor can aid several space missions. Often, satellite missions require multiple wireless links with the same radio, but the design of such antennas is challenging due to the mechanical constraints and the limited power aboard a CubeSat. In this paper, we present a unique reconfigurable antenna concept enabled by adhesive polyimide tapes. The presented antenna can switch from a conventional patch to a monopole-like antenna with minimal actuation complexity. This reconfiguration provides choices for polarization, pattern, and gain without use of active components for size, cost and power consumption reductions. The frequency of operation is S-band (2.4 GHz), and the antenna achieves S11 < −10 for both reconfiguration states. Measurements compare well with simulations in both states.

“…For instance, a dual-band reconfigurable origami antenna with changeable resonant frequency has been proposed by changing the folding states of a magic cube [15]. Liu et al introduced a reconfigurable multi-radii helical origami antenna by varying the helical origami height [16]. A dual–mode reconfigurable origami antenna provides directional mode(s) when the antenna is folded and omnidirectional when totally unfolded, with additional switching frequency ability; a dual–mode reconfigurable origami antenna [17], providing directional mode(s) when the antenna is folded and omnidirectional when totally unfolded as well as switching operational frequencies.…”

In this paper, we propose a bi-directional loop antenna array using magic cube origami. The proposed antenna array consists of three one-wavelength loop antenna elements with series feeding. Each loop antenna is realized on a single magic cube, and three cubes are connected in series to form the array. The three cubes can be easily folded and unfolded due to being constructed in the form of a magic cube origami. Antenna volume can be minimized for high mobility by folding the array, which radiates a bi-directional pattern with full volume when unfolded. The proposed antenna was designed at 1.39 GHz. When the single antenna is realized on the single cube, the peak gain is 4.03 dBi. The peak gain increased to 5.2 and 5.53 dBi with two and three antennas, respectively. Half-power beam width (HPBW) with three antenna elements decreased to 40° from 360° compared to the HPBW with the single antenna. The proposed antenna performance was assessed numerically and experimentally.
