摘　　要：首先通过引入射频识别技术和无线传感器网络技术相结合的一个新兴技术——射频识别传感器网络的概念,介绍作为其网络节点的射频识别传感器的种类及其基本工作原理,说明天线在其中的重要性;然后介绍了三种常用天线:线圈天线、对称振子天线、微带天线的工作原理,以及微带天线的设计过程;最后,在无线体温监控系统中,设计出通信距离控制在5 m范围以内的微带天线,并对结果进行了实际测量,符合设计要求。Radio frequency identification sensor network, which is a product of integrating radio frequency identification （RFID） with wireless sensor network （WSN）, is introduced in this paper. The principle of radio frequency identification sensor is analyzed, and the importance of the antenna is emphasized. Then three kinds of common antennae, namely coil antenna, dipole antenna and microstrip antenna, are discussed. Subsequently, according to requirement, we have designed a microstrip antenna in a wireless temperature-monitoring and controlling system. The measurement of factual effect showed the requirement was fulfilled.
