摘要：

提出一种新型结构的双频段射频识别(RFID)印刷天线.该天线由共面波导(CPW)馈电，工作于2.45 GHz和5.80 GHz 两个RFID频段.实测的阻抗带宽在2.45 GHz和5.80 GHz两个频段处,分别达到了32.0%和9.8%.该天线结构简单，尺寸为40 mm×40 mm，易与有源器件和微波单片集成电路集成在一起.最后,给出了该天线的详细设计及试验结果，并进行了讨论.

关键词: 射频识别；共面波导；双频段天线

Abstract:

A new design of dual-band radio frequency identification (RFID) printed antenna fed by a coplanar waveguide (CPW) is proposed, which operates in both 2.45 GHz and 5.80 GHz RFID bands. Its two measured impedance bandwidths are 32.0% at 2.45 GHz and 9.8% at 5.80 GHz respectively. The antenna has a simple structure sized 40 mm×40 mm, which is easy to be integrated with active devices and monolithic microwave integrated circuits. Details of the proposed antenna design and the measured results are presented and discussed.

Key words: radio frequency identification (RFID); coplanar waveguide; dual-band antenna
