摘要

本文设计了一种用于RFID应用的多层微带天线。该天线采用折叠式偶极子天线和基于环路的定向元件来实现，以提高整个天线结构的增益。该天线工作在2.4 GHz ISM频段，可实现6.4 dBi的高增益，适用于远场RFID读写器。详细研究表明，所设计的RFID读写器天线结构具有较强的近e场和h场以及良好的阻抗匹配性能。制作了天线，并通过回波损耗和辐射方向图的仿真和实测结果验证了天线的性能。

High Gain Folded Loop-based Multilayer Antenna at 2.4 GHz Band for Far-Field RFID Reader

This paper presents a multi-layer microstrip antenna designed for RFID application. This antenna is implemented by a folded dipole antenna with a loop-based directing element to increase the gain for the whole antenna structure. The proposed antenna operates at 2.4 GHz ISM band and achieves high gain of 6.4 dBi which is suitable for far-field RFID reader. Detailed study of the proposed RFID reader antenna exhibits that the designed antenna structure provides both strong near E-field and H-field and good impedance matching properties. The antenna was fabricated and its performance was validated by simulated and measured results with respect to return loss and radiation pattern.
