Description
Technical field
The utility model relates to a kind of smart card antenna and uses the double-interface card of this antenna, relates in particular to a kind of double-interface card antenna and uses the double-interface card of this antenna.
Background technology
Develop rapidly along with economy and information technology, economy and information interchange between people are more and more frequent, therefore people constantly invent various communication media, from finally storage card of early stage magnetic card, logic encryption card and now just at widely used Contact Type Ic Card.Security performance is high, simple in structure, versatility is good, Reading and writing instrument is simple and reliable, be convenient to the advantages such as maintenance because Contact Type Ic Card has, and is bringing into play irreplaceable effect in the transaction fields such as bank, postal service, telecommunications, securities trading, market consumption.But, due to the wearing and tearing between Contact Type Ic Card in use procedure and read-write heads, greatly shortened its useful life, the IC-card after wearing and tearing and the loose contact between card reader can cause again the transmission of data to be made mistakes; And in large flow place, the process of plug-in card can cause long wait.For this reason, people are applied to REID in IC-card, have produced non-contact IC card, are about to chip and antenna and are encapsulated in card inside fully, the surface of card does not have exposed chip contacts, by the mode of electromagnetic coupled, communicate in certain distance range with read-write heads, avoided the physical abrasion that causes because of the chip contact fully, convenient and swift, life-span is long, is widely used in the automatic fare collection systems such as public transport, subway, and the fields such as entrance guard management, proof of identification and stored value card.But, to be stuck in the serious applications of radio frequency interference limited due to non-contact IC, and the energy that electromagnetic coupled produces is low, transaction rate is fast, therefore the security performance of non-contact IC card is not high, add that there has been application technology and the infrastructure of a large amount of Contact Type Ic Cards in the industries such as finance, communication, therefore, the application of non-contact IC card is subject to a lot of restrictions.Based on this, a kind of merged Contact Type Ic Card and non-contact IC card two-fold advantage New Type IC Card---double-interface card arises at the historic moment.
Existing non-contact IC card is made and is normally adopted the ultrasonic wave wire winding that copper cash or aluminum steel are imbedded in the substrate layer of IC-card as antenna, and with the chips welding of substrate layer together.but, if the simple chip with non-contact IC card is placed on the IC-card surface while making it become double-interface card, in order to be applied to Non-contact Media Reader, the chip on the antenna of IC-card inside and IC-card surface need to be linked together, present method of attachment mainly contains two kinds, be that conductive rubber connects and is welded to connect, but these two kinds of methods of attachment all need to buy special-purpose double-interface card sealed in unit, and exist production efficiency low, the defects such as conforming product rate is low, and, because the copper cash as antenna or its wire diameter of aluminum steel are consistent, and the miniaturization along with IC-card, the wire of simple a kind of diameter is the frequency that can't well meet radiofrequency signal in the area of appointment, the Q value, the isoparametric requirement of electric capacity.Therefore, the radio-frequency antenna of existing double-interface card is to adopt etching technique to etch needed radio-frequency antenna figure on the composite material of copper or aluminium foil and PET mostly, or adopt printing technology printing conductive inks on the PET film materials to obtain needed radio-frequency antenna, above two kinds of techniques must be carried on PET base material or the better material of heatproof, to guarantee the stability of antenna pattern.Existing etching antenna technology is that the copper foil material of whole is etched away 90% copper with the mode of chemical etching, obtains antenna pattern.And this process will produce a large amount of chemical waste fluids, environment is caused serious destruction.And the Copper Foil that etching process is a large amount of with loss, 90% Copper Foil all is wasted, and production cost is increased substantially, and all very unfavorable to the protection of the utilization of resource and environment.Above two kinds of techniques must be carried on PET base material or the better material of heatproof, to guarantee the stability of antenna pattern, but be all to use bonding with base material and metal antenna of adhesive, but the adhesive that uses not is liptinite, constantly aging along with the variation of the conditions such as ambient temperature, humidity, thereby adhesive strength reduces the layering that causes base material and metal antenna, for use is made troubles and has improved user's purchase cost, and antenna while with chip, being connected welding method used also for processing, make troubles.
