Abstract
The invention relates to a high-frequency wireless radio frequency recognition antenna, and belongs to the technical field of wireless radio frequency recognition labels. The antenna is mainly characterized in that the number of turns of a coil on a base material is two, and a gap bridge wire penetrates through a gap of two pins of the front side coil. According to the antenna, the number of the turns of the front side aluminum coil is reduced, the mode that a back side gap bridge communication coil mode is changed into a mode that the coil is connected from the gap of the pins where a chip is placed, and accordingly an existing two-side antenna structure is changed into a single-side antenna. The complexity and production cost of a high-frequency (HF) antenna protection technology are greatly reduced, and the high-frequency (HF) antenna can be used in some special application industries such as fragile anti-counterfeiting labels. The application range is widened on the basis that performance quality of the existing high-frequency (HF) single-side antenna is guaranteed, economic benefits are improved, and high practicality is achieved.
Description
Technical field
The present invention relates to a kind of high frequency wireless radio frequency identification antenna, belong to wireless radio frequency identification mark technical field.
Background technology
Wireless radio frequency identification mark (RFID) can be divided into HF (high frequency) and UHF (hyperfrequency) two kinds, wherein HF (high frequency) product is because it reads apart from shorter, be generally used for in-plant application scenario, as access card, subway ticket, the aspects such as mass transit card, HF label is primarily of HF antenna and HF chip composition, mode inductively and read write line is adopted to carry out the response of information, and mode demand HF (high frequency) antenna inductively must be a loop, because loop must combine with two of a HF chip effective pin, therefore the joint of the other end in loop is generally realize by costing at the reverse side of antenna to pass a bridge.Existing this design has become a mindset of HF (high frequency) Antenna Design, i.e. two-sided HF antenna.
The complex manufacturing of existing this two-sided HF (high frequency) antenna, the positive back side of PET all need gluing and with aluminium foil or Copper Foil compound, after compound, the positive back side all needs to do to print, and the positive back side needs alignment, alignment can affect the performance of antenna partially, and pass a bridge and want to be communicated with front aluminum strip the technique needing and get through gap bridge in the back side in addition.Two-sided HF (high frequency) antenna is difficult to be used for some special industries simultaneously, as frangible anti-counterfeiting technology, because frangible antifalsification label is before making finished product, be affixed on other material after front aluminium foil or Copper Foil and PET need being peeled off, and two-sided antenna when this step and the back side pass a bridge peel off after be waste product, aluminium or Copper Foil can only be adopted at present as the raw material produced with antenna.
Summary of the invention
Object of the present invention is exactly the deficiency existed for above-mentioned prior art, provides a kind of high frequency wireless radio frequency identification antenna, is conducive to the complexity reducing high frequency antenna production technology, and can be used for as frangible more false proof special industries by the present invention.
The object of the invention is to be achieved through the following technical solutions, a kind of high frequency wireless radio frequency identification antenna, comprises base material, coil above base material, it is characterized in that, the coil above described base material is two circles, and gap bridge wire passes from the gap of the two pins of front coil.
The two pins of described front coil is at the rotation angle position of coil.
Described coil be through etching aluminium matter or adopt silver slurry or copper slurry printing.
The present invention is by reducing the number of turns of front side aluminum coil, place back side gap bridge being communicated with coil changes to and is communicated with from the pin gap of chip placement, thus change existing two-sided antenna structure into one side antenna, the present invention greatly reduces the complexity of HF (high frequency) antenna production technology, and make HF (high frequency) antenna can be used in some special application industries, as frangible antifalsification label.The present invention expands range of application on the basis of guaranteeing existing HF (high frequency) one side antenna performance quality, has very strong practicality.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present invention;
Fig. 2 is the cross section structure schematic diagram of the horizontal inner coil at Fig. 1 chip placement place;
Fig. 3 is the structure for amplifying schematic diagram in A portion in Fig. 1;
In figure, 1 base material, 2 coils, 3 HF chips, 4.1 gap bridge wires, 4.2 antenna leads, 4.3 antenna leads, A is partial enlargement district.
Embodiment
Further illustrate the present invention in conjunction with the accompanying drawings and embodiments, as Figure 1-3, the present invention is by base material 1, base material 1 is formed through the coil 2 of the aluminium matter of etching or employing silver slurry or the printing of copper slurry, coil above base material 1 is two circles, the electric capacity of the antenna that coil 2 is formed is consistent with the electric capacity of HF chip 3 itself, chip capacity in the market has three kinds, 17pF, 50pF and 100pF, multi-coil is easy to accomplish 17pF and 50pF, and so little electric capacity almost do not accomplished by two circles, the coil 2 in the present invention is because only having two circles, and its electric capacity can only accomplish 100pF.The below gap location of the antenna leads 4.2 and 4.3 welded H F chip 3 being placed in front coil 2 by existing back side gap bridge wire 4.1 passes by the present invention, the gap bridge wire 4.1 of HF chip 3 rest area is thinner, and the antenna leads 4.2,4.3 on side has larger interval, put the non-pinned district's not conducting due to chip after HF chip 3, therefore can not short circuit be caused and cause the inefficacy of tag performance.Existing two-sided antenna is become one side antenna by the present invention, thus in antenna production technology, decreases combination process, alignment and printing, gets through the operations such as gap bridge, because of the aluminium foil having lacked one side, from cost, also has larger reduction.
