AI Technical Summary
Technical Problem
Existing RFID tags cannot be effectively read on substrates that are difficult to process, such as those with high-loss dielectrics, organic materials, or metal surfaces, resulting in a limited reading range.
Method used
An RFID antenna structure is formed on a thermoplastic substrate, and a series of cavities are created on the substrate. An RFID chip is coupled to the antenna structure, which is located inside the cavity. The antenna structure is formed using a roll-to-roll process, and a conductive substrate can be used to cover the bottom surface of the cavity to improve coupling.
Benefits of technology
It enables RFID tags to operate effectively on substrates that are difficult to handle, improves reading performance, and adapts to complex surface environments.

Abstract
本申请题为“被设计为在难以处理的基板上工作的RFID标签”。公开了一种RFID标签装置，其被设计为在诸如具有高损耗的电介质表面、有机材料表面、或金属表面的难以处理的基板上操作。RFID标签装置包括以卷对卷工艺形成在热塑性基板部件的一侧上的RFID天线结构，其中RFID芯片耦合到RFID天线结构。然后基板部件被形变成一系列的腔，其中RFID天线结构位于腔内。具体地，RFID天线结构完全地定位在腔的顶表面上，或者部分地定位在腔的顶部中并且部分地定位在腔的边缘 / 底部上。
