摘　　要：为了广泛应用射频识别(RFID)技术,设计了一种标签天线。利用计算电磁场时域有限差分/矩量法的混合方法,分析了复杂环境中RFID天线的性能。将计算结果和实验进行比较,验证了混合方法计算结果的准确性,对RFID天线的工程设计有一定参考价值。To widely apply the radio frequency idenitifacation （RFID） to wireless local netwere in the compus, an antenna for passive RFID tags is designed. Properties of the antenna is analized in complex environment by using hybrid finate-difference tima-domain/method of moument in computational electromagnetism. Numerical results of the hybrid method have been validated by comparing to experimant. It has been proved that the design is suitible for a variety of RFID applications.
