The origami structure has caused a great interest in the field of engineering, and it has fantastic applications in the deployable and reconfigurable structures. Owing to the unique multi-stable states, here a typical hexagon-twist origami structure is fabricated via multi-material printing technology. The printed structure has multi-stable features and the stiffness of the deformable structure is dramatically reduced under thermal triggering. Such behavior causes an increase in the structural degree of freedom, allowing for self-deployment via releasing the prestored energy in the elastic crease. The response time and reaction time of the self-deployment process are also studied and illustrate the higher energy barrier of the folded state, the longer self-deployment time. Utilizing such unique features and design principles, a prototype of frequency reconfigurable origami antenna of nine diverse operating modes is subsequently designed and assembled with the hexagon-twist origami structure as the dielectric substrate. The antenna implements the cross-band from two different frequency bands, enabling to realize frequency reconfigurable under thermal condition.

折纸结构引起了工程领域的极大兴趣，并且在可部署和可重新配置的结构中具有出色的应用程序。由于独特的多稳定状态，此处通过多材料印刷技术制造了典型的六边形扭曲折纸结构。印刷结构具有多稳态特征，并且在热触发下可变形结构的刚度大大降低。这种行为会增加结构的自由度，从而通过释放弹性折痕中的预存能量来实现自我部署。还研究了自展开过程的响应时间和反应时间，并说明了折叠状态的能垒越高，自展开时间越长。利用这些独特的功能和设计原则，随后设计并以六边形扭曲折纸结构作为介电基板，设计并组装了九种不同工作模式的频率可重构折纸天线的原型。天线实现了来自两个不同频带的跨频带，从而能够实现在热条件下可重构的频率。
