“…The antenna operates at 0.48 GHz and 2.5 GHz in unfolded (dipole antenna) and fully folded state (conical spiral antenna), respectively. Most origami-based antennas are designed using paper which creates poor durability and performance stability [75]. Moreover, to accurately control the change in the antenna dimensions and shape is not easy due to the high flexibility nature of paper.…”

“…This also limits the range of the frequency reconfiguration to a couple of points. Therefore, in [75], a dipole antenna based on multi-material 3D printing technology is proposed, which can provide a continuous frequency reconfigurability from 0.95 GHz to 1.6 GHz through a precise structure manipulation by a robot.…”

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.

“…The FDM method is used to create 3D objects by heating a thermoplastic filament and extruding it layer by layer [20]. The SLA method can be used to fabricate 3D objects with a liquid photopolymer resin that is cured and solidified by an ultraviolet laser [21]. The FDM method has a simpler process than the SLA method because it only requires a suitable extruder and printing bed temperature that depend on the filament.…”

Despite the low cost and easy fabrication afforded by 3D printing technology, high dielectric loss of the 3D printing filament degrades the performance of 3D printed radio frequency electronics at high frequencies. In this paper, we propose a 3D-printed substrate-integrated waveguide (SIW) using a lossy polylactic acid or polylactide (PLA) filament. To minimize the insertion loss of the SIW, a non-uniform honeycomb is 3D-printed as the dielectric material of the SIW. The non-uniform honeycomb-shaped substrate is composed of large unit cells, which achieve low insertion loss (0.01 dB/mm) because of the low volume of the dielectric material. The performance characteristics of the proposed SIW was compared with those of SIWs made of solid and uniform honeycomb-shaped structures. The average insertion loss of the microstrip line-fed SIW with the proposed non-uniform honeycomb substrate is 0.92 dB in the frequency range of 1.97 to 3.35 GHz and those of the solid PLA and uniform honeycomb substrates are 2.49 dB and 1.38 dB, respectively. The proposed 3D-printed SIW additionally has the advantages of light weight and low cost.
