Embodiment Construction

[0038] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0039] A kind of RFID antenna of the present invention, its slurry is nickel slurry, wherein nickel slurry satisfies: viscosity between 85Pa s-115Pa s, linear resolution less than 200μm, resistivity less than 80mΩ / Sq, adhesion greater than or equal to 625N / cm 2 . Specifically, the existing RFID antenna is usually made by printing conductive paste on the substrate. In the present invention, the RFID antenna adopts nickel paste that meets the requirements on the ceramic substrate (nickel paste constitutes the antenna body), and then sinters it. Here Different proportions of nickel can be selected to debug a suitable nickel paste. Compared with the silver conductive paste that needs to print a sintered protective layer (...

Abstract

The invention relates to an RFID antenna, an RFID label and an RFID antenna manufacturing method, wherein the slurry of the RFID antenna is nickel slurry. The nickel slurry satisfies the conditions described as follows: viscosity is 85-115Pa*s; linear resolution is lower than 200 [mu]m; resistivity is lower than 80 m[omega] / Sq; and an adhesion force is higher than or equal with 625N / cm<2>. The RFID antenna, the RFID label and the RFID antenna manufacturing method have advantages of reducing RFID antenna cost, saving energy and reducing emission.

Description

technical field [0001] The invention relates to the field of antennas, and more specifically, to an RFID antenna, an RFID tag and a manufacturing method for the RFID antenna. Background technique [0002] Radio Frequency Identification (RFID) is an advanced form of automatic identification technology. As an advanced automatic identification technology, RFID has the advantages of large storage capacity, readable and writable, long recognition distance, fast recognition speed and long service life. , good environmental adaptability and simultaneous identification of multiple tags can be widely used in supply chain management, transportation management, industrial production management, animal identification management, access control, anti-counterfeiting, anti-theft, logistics, sports timing and other occasions . [0003] With the rapid development of the global Internet of Things, the annual demand for RFID tags will be in the hundreds of millions, and the low cost of RFID t...
