用于毫米波识别的无源基片集成波导标签

摘要

毫米波识别（MMID）技术在安全检查，信息识别，医药样品等应用中受到了越来越多的关注。作为全封闭结构，基片集成波导（SIW）具有高品质因数和低成本特性，应用于标签中具有较高的精度。目前，已经有SIW应用于无芯片MMID标签的例子。然而，现有的基于圆形SIW腔的标签通常具有较大的尺寸。整个标签的面积过大以至于在长编码情况下是不可接受的。因此，SIW标签小型化显得尤为重要。本论文中，一系列小型化SIW标签包括基于矩形SIW腔，四分之一模SIW腔以及复合左右手SIW腔将被一一展开讨论。与传统的MMID SIW标签相比，本文设计的标签能够显著提高电路利用效率。
