摘要
基于平面倒F天线模型,设计了一种小型的适合用于RFID系统射频标签的微带贴片天线,工作在0.915 GHz频率上。利用基于非均匀网格的时域有限差分方法(Non-uniform Fitine-difference Time-domain,nu -FDTD)对该天线的设计过程进行了建模和仿真,分析了辐射贴片结构的变化对天线的回波损耗的影响,进而对天线进行优化,使得这种平面倒F天线能够适应射频标签天线的需要。
A small microstrip patch antenna for the tag of RFID system is designed based on the model of planar inverted - F antenna. The designed antenna operates at the frequency of 0. 915 GHz and is modeled and simulated using non - uniform Finite - Difference Time - Domain （ nu - FDTD） algorithm. The influence of the variety of configuration of the radiating patch on the return loss is analyzed. On optimization, this antenna can meet with the requirements of tag antenna.
