A subwavelength antenna array design for time reversal communication

摘要: 基于时间反演电磁波的远场超分辨聚焦特性,设计了一种亚波长天线阵列,其天线单元刻蚀有微结构、单元间距为1/20工作波长且信道相互独立.在保证相似的辐射特性的条件下,该亚波长天线阵列对比于其他微结构刻蚀所组成的亚波长天线阵列,具有较好的远场超分辨率聚焦特性.为基于时间反演的高速率、高质量多天线通信提供了一种有效的终端天线阵列.

Abstract: Based on the super-resolution property of time reversal electromagnetic wave far-field focusing, a subwavelength antenna array is proposed. The elements of the array are etched into those that have microstructures, placed at an interval of λ/20 apart from one another, and have independent channels. Compared with the subwavelength antenna arrays, each of which is composed of other microstructure elements, the array, whose radiation property of individual antennae is similar to others, shows better super-resolution characteristic of far-field focusing. Therefore, an effective wireless terminal antenna array is provided for the high-speed and high- quality multiple-antenna communication using the time reversal technology.
