本文提出了一种适用于UHF频段860 - 960 MHz RFID应用的高性能2 × 2天线阵列，采用Butler矩阵波束形成网络。天线元件以及巴特勒矩阵使用微带技术实现。由于采用了原始的微带布线技术，设计非常紧凑，制造成本低。执行RFID批量测量证明了改进的阅读的可靠性的无源RFID标签堆叠在托盘中使用所提出的天线的概念与传统的单波束读取器天线的操作相比。
This paper presents a high performance 2 × 2 antenna array with a Butler matrix beamforming network for RFID applications in the UHF band 860 - 960MHz. The antenna elements as well as the Butler matrix are implemented using microstrip technology. Thanks to the applied original microstrip routing technique the design is very compact and has low fabrication costs. Performed RFID bulk measurements demonstrate an improvement of the reading reliability of passive RFID tags stacked in a pallet using the proposed antenna concept in contrast to the operation with a conventional singlebeam reader antenna.
