    • An RFID device includes conductive tabs, and a conductive structure, with a dielectric layer between the conductive tabs and the conductive structure. The conductive structure overlaps the conductive tabs and acts as a shield, allowing the device to be at least somewhat insensitive to the surface upon which it is mounted, or to the presence of nearby objects, such as goods in a carton or other container that includes the device. The dielectric layer may be a portion of the container, such as an overlapped portion of the container. Alternatively, the dielectric layer may be a separate layer, which may vary in thickness, allowing one of the conductive tabs to be capacitively coupled to the conductive structure. As another alternative, the dielectric layer may be an expandable substrate that may be expanded after fabrication operations, such as printing.
    • RFID设备包括导电突片和导电结构,其中介电层位于导电突片和导电结构之间。 导电结构与导电突出部重叠并用作屏蔽,允许该装置对其安装的表面至少有些不敏感,或者存在附近物体,例如纸箱或其他容器中的货物,包括 装置。 电介质层可以是容器的一部分,例如容器的重叠部分。 或者,电介质层可以是单独的层,其可以在厚度上变化,允许导电片中的一个电容耦合到导电结构。 作为另一替代方案,电介质层可以是可以在制造操作(例如印刷)之后扩展的可扩展基底。
