| 摘 要： | 为了研究满足工程需要的RFID标签天线，以2.45 GHz工作频段为例，给出了印刷偶极子标签天线以及其小型化设计。所设计的2.45GHz印刷偶极子标签天线的性能指标为：在驻波比小于1.5时，工作带宽约为450MHz；天线增益为1.4dB；天线尺寸大小为37mm×45.8mm。小型化后的天线尺寸缩小为31.8mm×28.5mm，面积减小了约47%，在驻波比小于1.5时，天线带宽约220MHz，天线增益为1.2dB。此外，给出了小型化天线的实测结果，并且与理论结果进行了比较，结果吻合良好。 |

| Abstract: | To meet the engineering requirement, a 2.45GHz RFID tag antenna and its minimization design are described. The antenna is presented with 450MHz bandwidth under the condition of VSWR less than 1.5, 1.4dB gain, and with the dimension of 37mm×45.8mm. After the minimization, the antenna shows a dimension of 31.8 mm×28.5mm, around 47% reduction of area compared to the original one. Its bandwidth is about 220MHz under the condition of VSWR less than 1.5, and 1.2dB gain. The measured results are compared with the simulated results, and good agreement is obtained. |
