Abstract

This paper presents design, numerical analysis and experimental investigation of an origami inspired X-band accordion waveguide that is aimed to create a flexible and adaptive solutions. The design process is conducted in a Finite Integration Technique (FIT) based microwave simulation software to model and simulate the proposed waveguide, and that shows structural benefits of origami technique based paper folding. Proposed waveguide model is numerically analyzed under both X and Y bending with 30˚, 60˚, 90˚ and 120˚ bending angle to provide its flexibility. Besides, the electric and magnetic field distributions were also obtained and explained in details to provide working mechanism of the proposed accordion waveguide. The S21 transmission characteristics between ports exhibits a decrease of 0.015 dB in numerical results, which is negligible and acceptable in applications. The experimental results demonstrate that the proposed waveguide has effective transmission characteristics within the 8–12 GHz X-band frequency range, with a satisfactory S21 transmission parameter. The numerical and experimental results show that proposed origami inspired accordion waveguide has a huge potential for application in dynamic microwave and satellite components.

受折纸启发的 X 波段手风琴波导的设计与实验研究

本文介绍了一种受折纸启发的 X 波段风琴式波导的设计、数值分析和实验研究，旨在创建一种灵活的自适应解决方案。设计过程通过基于有限集成技术（FIT）的微波仿真软件进行建模和仿真，并展示了基于折纸技术的折纸波导的结构优势。在 30˚、60˚、90˚ 和 120˚ 弯曲角度下，对拟议波导模型进行了 X 和 Y 弯曲数值分析，以提供其灵活性。此外，还获得了电场和磁场分布，并对其进行了详细解释，从而提供了拟议风琴波导的工作机制。数值结果显示，端口间的 S21 传输特性降低了 0.015 dB，这可以忽略不计，在应用中是可以接受的。实验结果表明，所提出的波导在 8-12 GHz X 波段频率范围内具有有效的传输特性，其 S21 传输参数令人满意。数值和实验结果表明，受折纸启发而提出的风琴式波导在动态微波和卫星元件中具有巨大的应用潜力。
