Abstract
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.
