摘要

本文提出了一种多模多输入多输出(MIMO)环形天线。通过特征模态分析，对环形天线的两种模式进行了识别和激励。通过将天线安装在折纸水弹图案上，两种模式的电磁特性通过折叠/展开同时重新配置。值得注意的是，在不同的辐射模式下获得了1.91 GHz、1.86 GHz和1.46 GHz的谐振频率。与采用传统空间分集技术的设计相比，通过在不同频率上激励多个正交模式，可以在更小的体积内实现MIMO操作。这种折纸多模天线为下一代通信系统提供了一种紧凑的自适应解决方案。

Design and Fabrication of an Origami Multimode Ring Antenna

In this work, a multimode multiple-input multiple-output (MIMO) ring antenna is proposed. Through characteristic mode analysis, two modes of the ring antenna are identified and excited. By mounting the antenna on an origami water-bomb pattern, the electromagnetic properties of both modes are simultaneously reconfigured through folding/unfolding. Notably, resonant frequencies at 1.91 GHz, 1.86 GHz, and 1.46 GHz are attained with different radiation patterns. By exciting multiple orthogonal modes at various frequencies, MIMO operation is realized within a reduced volume as compared to designs that employ traditional spatial diversity techniques. This origami multimode antenna provides a compact and adaptive solution for next generation communication systems.
