Abstract

A platform-tolerant RFID (Radio-Frequency Identification) tag is presented, designed to operate across the entire RFID band. This tag utilizes a small Artificial Magnetic Conductor (AMC) structure as a shielding element for an ungrounded RFID tag antenna. It can be easily mounted on various surfaces, including low permittivity dielectric materials, metal objects, or even attached to the human body for wearable applications. The key features of this RFID tag include its ability to be tuned within the worldwide RFID band, achieving a maximum theoretical read range of over 11 m. Despite its advanced capabilities, the design emphasizes simplicity and cost-effective manufacturing. The design and simulations were conducted using CST Studio Suite.

摘要

提出了一种平台兼容的射频识别（RFID）标签，其设计目的是在整个RFID频段内运行。该标签采用小型人工磁导体（AMC）结构作为未接地RFID标签天线的屏蔽元件。它可以轻松安装在各种表面上，包括低介电常数的介电材料、金属物体，甚至可附着在人体上用于可穿戴应用。这种RFID标签的关键特性包括能够在全球RFID频段内进行调谐，实现超过11米的最大理论读取范围。尽管具有先进的功能，但该设计强调简单性和经济高效的制造。设计和仿真使用CST Studio Suite进行。
