DNA-inspired frequency reconfigurable origami antenna using segmented rotation technique

초록

This article proposes a DNA inspired mechanically transformable frequency reconfigurable origami antenna. Further, the implementation of segmented rotation technology enables the folding-unfolding feature of the DNA inspired geometry. The tuning range of 145% with wide frequency sweep from 0.395 to 2.5 GHz is achieved for the proposed antenna. The proposed origami antenna was fabricated on a robust polyethylene terephthalate (PET) substrate, realizing the antenna conductive pattern using copper film. The reflection coefficients and radiation patterns of the fabricated antenna sample were measured for unfolded, partially folded, and completely folded states. The proposed origami antenna provides flexible design, efficient folding, compact packaging, and simple deployment.
