摘　　要：现有被动式RFID标签天线制造技术存在着不足:主流的蚀刻法工艺繁琐,产出速度慢,对环境有污染;印刷法使用的导电银油墨的成本居高不下,而且天线可靠性也存在问题;电镀法在大批量生产时才有成本优势。为此,提出了一种基于模切技术的天线制造方法:针对一款图案精细的超高频RFID天线,用两次模切排废的方法,得到了天线图形。天线与RFID芯片之间的连接依靠芯片模组完成。The main technologies on manufacturing the passive RFID tag antenna have some shortages： The etching process is cumbersome,low productive and environmentally unfriendly;by using the silver conductive ink,the printing method is of high cost,and the printed antenna has some reliability problems;the electroplating process is cost feasible in the high-volume production.To this end,propose a novel technique based on die cutting to manufacture the RFID antenna.A kind of UHF RFID antenna with fine pattern is fabricated by twice die-cutting and exhaust.The die module was employed to connect antenna to form a RFID tag.
