Electronic label

Abstract

The invention discloses an electrical label including a chip, an on-chip antenna and an offchip antenna, wherein the on-chip antenna is made by adoptign the interconnection line spiral winding of theintegrate circuit, and the on-chip antenna and the offchip antenna are in the transformer coupling way. The on-chip antenna adopts the monolayer multiturn spiral winding way of the metal interconnection coil with the radius smaller and the multilayer metal interconnection line upper and lower series way. The on-chip antenna is made by combining the multiturn spiral winding way of the peer metal interconnection line coil with the radius smaller and the adjacent metal interconnection line upper and lower series way. The invention adopts the on-chip sensibility antenna and the offchip condenser antenna transformer coupling way, reduces the required positioning accuracy when connecting the antenna and the chip, meanwhile greatly reduces the encapsulating cost of the label and enhances the performance of the chip.

Description

technical field [0001] The invention relates to an electronic tag in the radio frequency identification technology. The electronic tag includes a chip, an on-chip antenna and an off-chip antenna. Background technique [0002] In recent years, automatic identification methods have been rapidly popularized and promoted in many service fields, in the sales of goods and logistics distribution, in the commercial sector, in the fields of production enterprises and material circulation. [0003] Barcodes, also known as paper tapes, caused a revolution in the field of identification systems and became widely used a few years ago. Today, this kind of barcode can no longer meet people's needs in more and more cases. Although the bar code is very cheap, its disadvantage is that the storage capacity is small and cannot be rewritten. [0004] A technically optimal solution is to store the data on a silicon chip. In daily life, IC cards with contact rows, such as telephone IC cards, ba...

Today, this kind of barcode can no longer meet people's needs in more and more cases

Although the bar code is very cheap, its disadvantage is that the storage capacity is small and cannot be rewritten

Since the pad area of ​​the chip is very small, high positioning accuracy is required when connecting the antenna and the chip, making the design of the packaged instrument more difficult and costly
