Coupling radio frequency identification label and manufacturing method thereof

Abstract

The invention provides a coupling radio frequency identification label. The label comprises an RFID chip, an annular antenna electrically connected with the RFID chip, and a conductive pattern which gets close to and is coupled to the annular antenna. According to the invention, by setting the conductive pattern with a signal amplification function, the radio frequency function of the antenna canbe improved, so the coupling radio frequency identification label can be identified by a reader-writer in a quite stable manner, and the identification distance is quite long.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a coupled radio frequency identification tag and a manufacturing method thereof. Background technique [0002] Now RFID flexible electronic tags generally adopt Flip-Chip reverse packaging technology. Flip Chip is not only a chip interconnection technology, but also an ideal chip bonding technology. IBM has developed and used this technology as early as 30 years ago. technology. But until recent years, Flip-Chip has become a frequently used packaging form in the field of high-end devices and high-density packaging. [0003] Today, the application range of Flip-Chip packaging technology is becoming wider and wider, and the packaging forms are becoming more diversified, so the requirements for Flip-Chip packaging technology are also increasing. At the same time, Flip-Chip also poses a series of new serious challenges to manufacturers, providing reliable support for packagin...
