| 摘 要： | 2.45 GHz频段是RFID常用的频段之一,针对该频段的一款读写器天线进行了详细的分析并进行了改进。借助ANSOFT HFSS 10.0计算软件对天线系统进行了仿真分析,在样本天线的基础上,通过对贴片边缘开槽,使天线在保持高增益的情况下,在更宽的频带上具有更好的稳定性,同时也减小了天线的尺寸,使天线整体性能更加完善。

| Abstract: | 2.45 GHz band is one of the frequency bands which is commonly used in RFID.A reader antenna working at the band is analysed and improved.The antenna system is simulated and analyzed by the aid of ANSOFT HFSS10.0 calculation software.By slotting the patch edge of the sample antenna,the antenna has better stability at a wider band in the case of keeping high gain,and the size of the antenna can be reduced in this way.Therefore the overall performance of the antenna is perfect. |
