| 中文摘要: |
| 标签天线是RFID系统的关键部件, UHF频段RFID系统多采用偶极子天线及其变形型式。针对目前标签天线小型化的实际要求，本文设计了一款对称弯折偶极子天线，并对天线的主要结构参数对天线阻抗的影响作了仿真分析。针对具体的标签芯片,设计了尺寸仅为26.4mm?8mm?.8mm的标签天线.该尺寸具有明显的小型化优势，具有较好的S11特性和全向性。其10dB带宽包含了整个UHF频段，具有宽频带特性。 |

| The tag antenna is a key component of RFID systems. Dipole antenna and its modification types are widely used in UHF band. Currently, Miniaturization was needed in tag antenna. In this paper, a symmetric bending dipole antenna was presented，the main structural parameters which influenced the impendence of antenna was analyzed. As a special tag chip, a tag antenna, which size was 26.4mm?8mm?.8mm, was designed. The antenna has a advantage of Miniaturization. The S11 performs well, the antenna is omni directional. The 10dB bandwidth includes the whole UHF band, with broadband characteristics. |
