摘　　要：为满足射频识别(RFID)阅读器小型化的要求,提出一种新的基于左手材料的小型化微带贴片天线.贴片天线采用圆环结构,将地板开槽,形成左手材料特性的8型结构,对天线的特性参数进行仿真计算,仿真结果表明天线具有较好的回波损耗特性,尺寸比普通矩形贴片天线减小了90%,方向性也符合RFID技术对天线的要求,且该贴片天线结构简单,易于实现.To meet the design requirements of the miniaturization of radio frequency identi- fication （RFZD） reader, It is presented that metamaterials is utilized to miniaturize the micro- strip patch antenna, Through optimization, it is simulated that antenna has a good characteris- tic of S（1,1~. The size of the patch is reduced by 90~ compared to conventional rectangle micro- strip patch antennas. The directivity of the antenna performance meets the requirements o~ RFID antenna. Compared with the traditional design, the new one whose structure is easy and it can be easily realized.
