Problems solved by technology

The advantage of this kind of anti-metal tag is that the frequency band is wide, and the disadvantage is that the recognition distance is relatively short, which is generally half of the recognition distance of the same size non-anti-metal tag made by the same chip.
Moreover, such anti-metal labels are generally not resistant to high temperature and corrosion, and cannot be used for a long time in harsh environments such as high temperature, humidity, strong acid and alkali.

Abstract

The invention discloses a long distance ultrahigh frequency RFID anti-metal label and a manufacturing method thereof. The label comprises a substrate. An antenna-shaped metal thin layer is etched or sintered in the substrate, and then the metal thin layer is welded with a chip to manufacture the long distance ultrahigh frequency RFID anti-metal label. The label antenna is an ultrahigh frequency RFID anti-metal label including short circuit through holes. Through the invention, the ultrahigh frequency RFID anti-metal label which is high temperature resistant, corrosion resisting and long in identification distance is realized.

Description

technical field [0001] The invention relates to radio frequency identification (Radio Frequency Identification, RFID) technology, in particular to a long-distance ultra-high frequency RFID anti-metal tag and a manufacturing method thereof. Background technique [0002] At present, most UHF RFID anti-metal tags sold in the market are in the form of unipolar oscillators without vias or dipole oscillators with closed-loop structures. The advantage of this kind of anti-metal tag is that the frequency band is wide, and the disadvantage is that the recognition distance is relatively short, which is generally half of the recognition distance of the same size non-anti-metal tag made by the same chip. Moreover, such anti-metal labels are generally not resistant to high temperature and corrosion, and cannot be used for a long time in harsh environments such as high temperature, humidity, strong acid and alkali. Therefore, for long-term work in harsh environments such as high temperat...
