Description
Technical field
The utility model refers in particular to a kind of general-purpose chip based on ultra-high frequency radio-frequency (RF) identification logistic label about a kind of general-purpose chip.
Background technology
Radio-frequency (RF) identification (RFID) label comprise the circuit (for example microchip) of store various kinds of data and be used for inputting data or with the data transmission of storage to the antenna that is connected with described circuit of reader.The RFID label with receive from the signal of antenna transmission and send the reader of data to the special purpose computer that arithmetical unit is obtained and analyze the RFID label data.
Be called in this area in the various data that the RFID label is stored in the process of " access " and read by the wireless telecommunications between RFID label and the reader.The RFID label is attached to each project, for example product, goods, material, marketable securities, animal and plant, thereby improve produce, dispensing and the efficient of selling.
Fig. 1 is the structural representation of traditional RFID label 11.
In the RFID label, the structure of antenna and shape are identified (namely reading) scope along with used frequency band or required maximum wireless and are changed.
Fig. 1 has represented the conventional example RFID label 11 of operation in high frequency (HF) scope at about 13.56MHz, RFID label 11 comprises rectangular substrate 13, guarantee to be in the conducting film 21 of substrate 13 central authorities, be installed on the upper surface of conducting film 21 and the chip 19 that is connected with conducting film 21 electricity, and the tours antenna 15 that is connected with chip 19 electricity by conducting film 21 round chip 19 and two ends.One end of tours antenna 15 directly links to each other with conducting film 2l, and the other end links to each other with conducting film 21 indirectly by web joint 17.
Because antenna 15 has occupied the main region on substrate 13 surfaces of traditional RFID label 1l, so the whole surface of label 11 can not narrow down, this can limit the potential application of label 1l.In addition, shown in antenna 15 sustain damage easily or abrade, cause short circuit or open circuit.And if any part of antenna 15 is impaired, RFID label 1l can be ineffective.
Tradition RFID label volume is large, and structure is complicated, and integrated level is lower, and power consumption is high; Adopt traditional conciliation scheme, can not process the electronic tag echo speed of different rates, the ability of identification electronic tag; The signal gain amplifier is fixed, and can not adapt to the echoed signal of unlike signal intensity; What adopt is the analog filtering technology, poor anti jamming capability.
The utility model content
The utility model purpose is to overcome above-mentioned the deficiencies in the prior art, provides that a kind of volume is little, integrated level is high, and recognition capability is strong, strong adaptability, the RFID general-purpose chip that antijamming capability is strong.
For achieving the above object, the utility model provides a kind of general-purpose chip based on ultra-high frequency radio-frequency (RF) identification logistic label, comprising:
One substrate, described substrate central authorities are provided with a chip, and the upper surface of described chip is provided with a plurality of contacts;
The complex root antenna, the first end of described antenna is connected with a described contact electricity, and the second end of described antenna is crooked to the direction of described substrate.
Further, the first end of described antenna by conductive adhesive on described contact.
Further, described conducting resinl comprises silver.
Further, in the described complex root antenna, have at least two to be oppositely arranged in opposite direction.
The utility model is based on the general-purpose chip of ultra-high frequency radio-frequency (RF) identification logistic label, antenna with a plurality of weak points replaces tours antenna, thereby reduced the size of label, owing to select the high hardware cell of integrated level, greatly reduced the volume of the general-purpose chip of ultra-high frequency radio-frequency (RF) identification logistic label, so that general-purpose chip miniaturization and the modularization of ultra-high frequency radio-frequency (RF) identification logistic label, power consumption also obtains corresponding reduction, the convenient embedding in the middle of the miscellaneous equipment.Can be fast and easily implement antenna is bonded to technique on the chip.Have that volume is little, integrated level is high, recognition capability is strong, strong adaptability, the characteristics that antijamming capability is strong.And have following innovation advantage: 1. what adopt is the induction type data acquisition, simple to operate, convenient.2. have unique ID code, durable in use, information can not be altered or copy.3. carry out the intelligent-tracking management, to accomplish timely prevention and control, trace to its source, product loss is reduced to minimum point.
