标签天线的优化设计是实现标签小型化的关键。以2.45 GHz的碎片天线为设计对象，利用遗传算法对尺寸受限的标签天线结构进行优化设计，采用FDTD算法对天线的阻抗特性和辐射特性进行了仿真分析，得到与标签芯片相匹配的输入阻抗，通过与实物的对比分析，验证了设计方法的正确性。

Optimal design of the tag antenna is the key of tags miniaturization. An optimized design of 2. 45 GHz RFID tag antenna is proposed by using Genetic Algorithm. The designing proposed antenna is simulated based on FDTD method and then the impedance and radiation characteristics is given and validated by the experiment.
