Abstract
The utility model discloses a miniature metal-resistant electronic tag which comprises an antenna structure, a radio frequency identification (RFID) chip and a substrate. The antenna structure is an asymmetric structure and includes a first radiation sheet, a second radiation sheet and a reflection sheet. The first radiation sheet is disposed on the top of the substrate. The second radiation sheet and the reflection sheet are on the same plane and are disposed at the bottom of the substrate. A gap is arranged in one end of the first radiation sheet and the RFID chip is connected in the gap. A first short circuit connector is arranged between the first radiation sheet and the second radiation sheet and is connected with the first radiation sheet and the second radiation sheet. A second short circuit connector is arranged between the first radiation sheet and the reflection sheet and is connected with the first radiation sheet and the reflection sheet. The miniature metal-resistant electronic tag has a size less than one tenth of an operating wavelength and a thickness of only 1 to 5 mm, and therefore the miniature metal-resistant electronic tag is small in size and low in cost, has a long reading distance, and can be applied to surfaces of metal articles such as asset management devices, guns, jewellery, etc.
Description
Technical field
The utility model relates to a kind of electronic tag, relates in particular to a kind of miniature anti-metal electronic tag.
Background technology
Radio-frequency (RF) identification is RFID(Radio Frequency IDentification) technology, claim again electronic tag, radio frequency identification, it is a kind of communication technology, can identify specific objective and read and write related data by radio signals, and without setting up machinery between recognition system and specific objective or optics contacts.In microwave communication field of radio frequency identification, be unable to do without electronic tag.Because electronic tag has at a distance, dynamically descend the ability of reading information, so used by increasing industry.Yet, because electromagnetic wave all can be absorbed and reflection by metal, cause common electronic tag cannot be correctly validated in metal surface, affect label and normally work
At present, one of people's employing scheme is the distance that increases electronic tag and metal environment, and common label, in the distance more than wavelength apart from 0.05 of sheet metal, could recover the radiation characteristic of its free space.But now requiring more than the thickness of label reaches 16mm, increases label volume greatly, also increases cost of manufacture, and affects label and be employed the conformal of article.
It is the microstrip antenna structures that adopt both-end to load that people adopt two of scheme, it is substrate that label relies on pcb board medium, descend two sides to lay two parallel dipoles thereon, by short circuit hole, be electrically connected endways, antenna structure is approximately and amounts to a period of time, this kind of structure has two groups of antenna models, and a period of time on medium top is symmetrical dipole, a period of time of medium bottom and sheet metal coupling energy, antenna effectively suppresses electromagnetic reflection.But the thickness of this kind of structure is about 2-5 millimeter, reduce a lot, but its length is still about the half wavelength of frequency of operation than the first structural volume, cannot be applied in the little metal environment such as gun, jewelry.
Therefore, current electronic tag volume is larger, and inconvenience is installed, and has the metal environment of strict demand cannot apply etc. to size.
Utility model content
The purpose of this utility model is to overcome the defect of prior art, and a kind of miniature anti-metal electronic tag is provided, and makes the size of label be less than 1/10th of operation wavelength, and thickness 1～5mm only, and size is little, and cost is low; And read apart from far away, can use on metal surfaces such as asset management, gun, jewelry.
The technical scheme that realizes above-mentioned purpose is:
A kind of miniature anti-metal electronic tag of the utility model, comprises antenna structure, RFID chip and substrate, and wherein, described antenna structure is unsymmetric structure, comprises the first radiation fin, the second radiation fin and reflector plate, wherein:
Described the first radiation fin is at substrate top, and described the second radiation fin and reflector plate are that same plane is at B.B.P;
There is a breach one end of described the first radiation fin, for connecting RFID chip;
Between described the first radiation fin and the second radiation fin, be provided with the first short circuit connector, described the first short circuit connector connects the first radiation fin and the second radiation fin;
Between described the first radiation fin and reflector plate, be provided with the second short circuit connector, described the second short circuit connector connects the first radiation fin and reflector plate.
Above-mentioned miniature anti-metal electronic tag, wherein, described the second radiation fin and reflector plate are same plane and are all arranged on substrate bottom surface.
Above-mentioned miniature anti-metal electronic tag, wherein, is provided with gap between described the second radiation fin and reflector plate and separates.
Above-mentioned miniature anti-metal electronic tag, wherein, the surface of described antenna structure is provided with insulation course.
Above-mentioned miniature anti-metal electronic tag, wherein, the material of the first described short circuit connector is metal material.
Above-mentioned miniature anti-metal electronic tag, wherein, the material of the second described short circuit connector is metal material.
The beneficial effects of the utility model are: the utility model provides a kind of miniature anti-metal electronic tag, this structure can greatly be dwindled antenna size, the size that makes label is only 1/10th of operation wavelength, thickness is 1～5mm only, size is far smaller than general electronic tag, therefore antenna volume is little, and cost is low, is convenient to hide place; And read apart from far away, can use on metal surfaces such as asset management, gun, jewelry.
