Abstract

The invention discloses an ultrahigh-frequency RFID antenna, a manufacturing method, and an RFID tag employed by the ultrahigh-frequency RFID antenna. The antenna comprises an antenna layer, a resin layer and high-temperature-resistant anti-corrosion paper, wherein the antenna layer, the resin layer and the high-temperature-resistant anti-corrosion paper are sequentially stacked from the top to the bottom. The antenna layer is provided with a chip in a binding manner. The manufacturing method for the antenna comprises the steps: 1), coating: coating the surface of the high-temperature-resistant anti-corrosion paper with resin; 2), attaching: enabling the antenna layer to be attached to the high-temperature-resistant anti-corrosion paper; 3), drying: drying an antenna semi-finished product; 4), etching: carrying out the etching of an antenna pattern on the antenna layer of the antenna semi-finished product; 5), chip binding: enabling a chip to be bound on the antenna layer, and obtaining the ultrahigh-frequency RFID antenna. According to the invention, the high-temperature-resistant anti-corrosion paper is employs as a frangible layer, and the thickness of the high-temperature-resistant anti-corrosion paper is stable. The high-temperature-resistant anti-corrosion paper is resistant to high temperature and corrosion, is liable to be damaged, and is suitable for the replacing of a PET film as a bearing frangible base material of an electronic tag antenna and chip binding.

Description

technical field [0001] The invention relates to an ultra-high frequency RFID antenna, a manufacturing method and an applied RFID tag, and belongs to the field of radio frequency technology. Background technique [0002] As a data carrier, electronic tags can play the role of identification, item tracking and information collection. RFID electronic tags have the advantages of fast response, small size, large memory, high security and low pollution, and the combination of RFID technology with Internet and communication technology can realize item tracking and information sharing on a global scale. [0003] For the existing fragile RFID electronic tags, the upper surface layer is a fragile layer, and the lower layer is a high-strength film. In conventional technology, PET film is usually used for the fragile layer. The melting point of PET film reaches about 250°C, which is suitable for making electronic labels. However, the relatively high cost of PET film greatly increases t...
