Background technology
Press, RF identification (Radio Frequency Identification, be called for short RFID) technology, be called RFID tag (RFID tag) again, be a kind of communication technology, can make a recognition system (as: reader, reader), see through electromagnetic wave signal, discern a specific objective, and read and write related data in this specific objective, and between this recognition system and specific objective, need not to set up contacting of machinery or optics fully.With respect to bar code (Barcode) technology, RFID tag can be stored the information and the certain information processing capacity of tool of a constant volume, and recognition system can be by radio signal with certain data transmission rate and RFID tag exchange information.Therefore, the applicable field of RFID tag is very extensive, comprising:
(1) anti-counterfeiting technology of banknote and product;
(2) cermet of identification, the traffic permit and admission ticket;
(3) electronic toll collection systems reaches EasyCard logical and Taiwan as eight of Hong Kong;
(4) domestic animal or wild animal identification; And
(5) patient identification and electronic health record.
In classification, RFID tag can be divided into passive type, semi-passive (being also referred to as semi-active type), active three classes, and its main character and difference are as shown in following:
(1) passive type: itself does not have internal power supply RFID tag, and its internal integrated circuit system drives by the electromagnetic wave that receives, and these electromagnetic waves are to come from reader.When the passive radio frequency identification label receives the electromagnetic wave signal of sufficient intensity, can return data to reader.
(2) semi-passive: be similar to passive type, but be provided with a compact battery more in it, its electric power just can drive the integrated circuit in the label, makes integrated circuit in running order, to increase the speed of response and the efficient of RFID tag.
(3) active: different with passive type and semi-passive is that active tag itself has the internal electric source supply, in order to the required power supply of supply internal integrated circuit, to produce the fgn signal.Active tag can have long distance and the bigger memory span of reading usually, to store the appended message that reader was sent.
The RFID tag that the present invention is alleged in the following description mainly means the passive radio frequency identification label, and this kind label has become the main product in RFID tag market at present, and has following advantage:
(1) can hold more data volume;
(2) long communication distance is arranged;
(3) be difficult to duplicate;
(4) environmental change there is higher suffertibility; And
(5) reader can read a plurality of RFID tag simultaneously.
Every excellent properties based on RFID tag, RFID tag has been widely applied to the logistics management field at present, see through RFID tag, can reach the immediately monitoring of each link such as production, transportation, dispensing, sale, make the user can grasp the relevent information (as: information such as product type, manufacturer, size, quantity, arrival point, accepter) of product exactly.Shown in Figure 1, be general commercially available RFID tag 10, this RFID tag 10 is made of a dual-mode antenna 11, a chip 12 and a base material 13, and this base material 13 generally is to make with polyimide (Polyimide) material, and this dual-mode antenna 11 is to be laid on this base material 13.The general practice is after attaching the last layer Copper Foil on the base material 13, according to prior design-calculated antenna pattern, to form this dual-mode antenna 11 with etching technique more earlier.The two ends system of this chip 12 is connected with the feed side of this dual-mode antenna 11 respectively, in order to do just this chip 12 can be through this dual-mode antenna 11 reception or transmitted radio signal.
When this RFID tag 10 is pasted to non-conductive object (as: plastic cement, glass etc.), this RFID tag 10 can keep its normal signal transmission effect, and can exchange information with reader in the design-calculated scope (distance) in advance, only, be labelled to the surface of metal object when this RFID tag 10, and during these dual-mode antenna 11 electromagnetic signals, this metal object just can produce a reflection pulse wave because of the theory of videoing (Image Theory).The phase place of this reflection pulse wave is opposite with the phase place of the electromagnetic wave signal of these dual-mode antenna 11 emissions, so can with this electromagnetic wave signal generation destructive interference, make that this electromagnetic wave signal is destroyed, and can't transfer to reader, cause reader can't normally read information in this RFID tag 10.So-called destructive interference means that the crest of a ripple and the trough of another ripple arrive at same place simultaneously, when two ripples overlap, synthetic wave amplitude is less than the composition wave amplitude, if the lucky anti-phase interference of two ripples then can produce minimum amplitude, this phenomenon is called complete destructive interference.
Hold, at present in many logistics systems, for keeping waiting to send the article drying, avoid waiting to send article to get rusty or mouldy because of moisture, or for mating part article to be sent can not be subjected to the characteristic of light direct projection, user (logistics system dealer) must be with metal bag (as: aluminium foil bag) packing article to be sent, to carry out conveying program, and because the metal bag has advantages such as intensity height, toughness height, protection against the tide, so day by day be popularized for the logistics system in each field.Yet above-mentioned RFID tag 10 is but because of above-mentioned reflection pulse wave problem, and can't be applicable on the metal bag.If the user is attached to this RFID tag 10 on the metal bag, very likely cause the transmitting range of this RFID tag 10 to drop near 0 meter, make reader almost can't read this RFID tag 10, cause the user can't manage article respectively to be sent exactly, very undesirable.
