摘要

本文设计并分析了一种适用于欧洲UHF RFID频段(即865MHz - 868MHz)的新型紧凑型阅读器天线。所提出的介质谐振器天线(DRA)由微带线/槽馈电和高介电常数(εr = 30)的半介质谐振器组成。仿真结果显示了令人满意的性能和尺寸。天线工作范围为857 ~ 885 MHz，因此覆盖了欧洲UHF RFID频段，其线极化辐射方向图提供了3.75 dBi的实现增益。对所提出的结构的反射系数、辐射方向图和天线增益进行了研究，两个模拟器的模拟结果基本一致。

Compact half-cylindrical dielectric resonator antenna for UHF RFID applications

In this paper, a new compact Reader Antenna is designed and analyzed in European UHF RFID band (i.e., 865MHz - 868MHz). The proposed Dielectric Resonator Antenna (DRA) is composed of microstrip line/slot feed and a half dielectric resonator made from a high-permittivity (εr = 30). The simulated results show satisfactory performance versus size. The antenna works from 857 to 885 MHz, thus covering the European UHF RFID Band, and its linearly polarized radiation pattern provides a 3.75 dBi realized gain. The reflection coefficient, radiation pattern, and antenna gain of proposed configuration are studied, and reasonable agreement between the two simulators results is observed.
