摘　　要： 分析了缝隙弯折次数、高度、位置、宽度和缝隙平片大小对缝隙天线谐振特性的影响.仿真结果显示,缝隙的弯折次数和高度对其谐振频率影响显著.最后,提出了一款UHF射频识别标签用的缝隙天线,制作了相应的实物天线.仿真与测试结果说明所设计的天线基本满足RFID标签应用要求. The influences of bend times, height, position, width and conductor size on resonant characteristics of slot antenna are analyzed. The simulation results of MOM （ method of moment） show that both bend times and height of slot antenna can efficiently reduce the resonant frequency. Consequently they can also efficiently miniaturize the size of RFID tag antenna. Finally, one slot antenna used as RFID （ Radio frequency identification） tag antenna at 915 MHz band is presented. Both simulated and measured results show that the designed antenna is satisfied for RFID application.
