Abstract
The utility model relates to field of antenna, particularly relates to ultrahigh frequency reader-writer Linear Double near field antenna.Comprise cabinet, include file interlayer on described cabinet, described file interlayer comprises the wall of horizontal distribution, and above described wall or inside is placed with antenna body.Also comprise the object be placed in cabinet, described object top layer is distributed with one deck RFID label tag.Beneficial effect: for file, file is labelled at the lower left corner (lower right corner also can) RFID, when then putting into cupboard, will the position of label be had just in time to be placed on above antenna, during such Antenna Operation can preferably least interference scan rfid label.Thus the management realized file.
Description
Technical field
The utility model relates to field of antenna, particularly relates to ultrahigh frequency reader-writer Linear Double near field antenna.
Background technology
The antenna majority that existing ultrahigh frequency reader-writer uses is linear polarization, circular polarisation two kinds.
Linear polarization scanning distance is several centimetres to tens centimetres, and scanning area also only has several centimetres to tens centimetres;
The maximum distance that circular polarized antenna is pursued reaches several meters even tens meters, but have lost in-plant effect, and scanning area also just will can reach maximum in larger distance;
Scan closely, article in the scope of large regions (tens centimeter length), comparatively difficult by these two kinds of antennas, cost is higher.
In addition, for some file management inconvenience, a kind of advanced management structure is not had.
Utility model content
The object of utility model: in order to provide a kind of ultrahigh frequency reader-writer Linear Double of better effects if near field antenna, specific purposes are shown in multiple substantial technological effects of concrete implementation section.
In order to reach as above object, the utility model takes following technical scheme:
Ultrahigh frequency reader-writer Linear Double, near field antenna, is characterized in that, comprises cabinet, include file interlayer on described cabinet, and described file interlayer comprises the wall of horizontal distribution, and above described wall or inside is placed with antenna body.
The further technical scheme of the utility model is, also comprises the object be placed in cabinet, and described object top layer is distributed with one deck RFID label tag.
The further technical scheme of the utility model is, described pars intramuralis comprises space, and antenna body is placed in a telescopic shaft end, and telescopic shaft side is telescope motor, and telescope motor is placed on cabinet.
The further technical scheme of the utility model is, described antenna body comprises two, and one is individual towards the next one upward, and described wall is transparent wall.
The further technical scheme of the utility model is, described antenna body is RFID radio frequency identification identification antenna.
Adopt the utility model of as above technical scheme, following beneficial effect is had: for file relative to prior art, file is labelled at the lower left corner (lower right corner also can) RFID, when then putting into cupboard, to the position of label be had just in time to be placed on above antenna, during such Antenna Operation can preferably least interference scan rfid label.Thus the management realized file.
Accompanying drawing explanation
In order to further illustrate the utility model, be described further below in conjunction with accompanying drawing:
Fig. 1 is utility model structural representation;
Fig. 2 is the scheme section structural representation that utility model is added;
1. cabinet; 2. spatial accommodation; 3. antenna body; 4. telescopic shaft; 5. telescope motor; 6. wall; 7. held beneath space.
Embodiment
Be described embodiment of the present utility model below in conjunction with accompanying drawing, embodiment does not form restriction of the present utility model:
Ultrahigh frequency reader-writer Linear Double, near field antenna, is characterized in that, comprises cabinet, include file interlayer on described cabinet, and described file interlayer comprises the wall of horizontal distribution, and above described wall or inside is placed with antenna body.Its implementation procedure is as follows: cupboard divides by measure 2 layers of cabinet and 4 layers of cabinet, every layer of ALARA Principle 100 parts of files.Wherein crucial article Real-time Monitor Management is implemented by this antenna exactly, long 80 centimetres of antenna shapes, wide 20 centimetres, thick 0.8 centimetre.Be placed on the laminate of cupboard, by inboard.
File is labelled at the lower left corner (lower right corner also can) RFID, when then putting into cupboard, will the position of label be had just in time to be placed on above antenna, during such Antenna Operation can preferably least interference scan rfid label.Thus the management realized file.
Also comprise the object be placed in cabinet, described object top layer is distributed with one deck RFID label tag.More than be exemplified as file, but clearly, this patent is not limited to file.
Composition graphs 1, described pars intramuralis comprises space, and antenna body is placed in a telescopic shaft end, and telescopic shaft side is telescope motor, and telescope motor is placed on cabinet.As further modification, antenna body shift position can also be said, telescopic shaft flexible position, thus identify one by one and manage at a distance, greatly reduce human cost.
As further improving, described antenna body comprises two, and one is individual towards the next one upward, and described wall is transparent wall.Namely, time file is placed on held beneath space, can place RFID above file more labelled, two antenna bodies carry out identifying and managing simultaneously.
Equally, above antenna body can be replaced by a box, and antenna can be placed on wherein.
Described antenna body is RFID radio frequency identification identification antenna.Now patent name also can be described as: a kind of novel cabinet.
In a creative way, each effect above independently exists, and can also complete the combination of the above results with a nested structure.
The technology identified due to RFID belongs to prior art, and therefore this place repeats no more.As further expanding, do not affect above scheme, this place further illustrates a kind of improvement opportunity.
Not shown part details.
Composition graphs 2, antenna substrate material is copper or aluminium, and thickness is no more than 1 millimeter, and width is no more than 20 millimeters;
Connecting feeder line access antenna substrate is symmetrical access, utilize the feature of read write line each antenna port order scanning, antenna is respectively worked 1 time in the two directions, namely respectively work once respectively as RF1 and RF2, achieve left and right both direction to make up mutually, make whole antenna area scan effective balance efficient.
Further, the cupboard of management confidential document, article, the technology such as integrating RFID technology, biometrics identification technology, gate inhibition, builds up a set of management system.System synthesis utilizes each equipment, reaches the Real-time Monitor Management to putting into cabinet article, and the rights management of operating personnel is managed the record management of article and personnel.
It should be noted that, multiple schemes that this patent provides comprise basic scheme own, separate, mutually do not restrict, but it also can combine when not conflicting mutually, reaching multiple effect and jointly realizing.
More than show and describe ultimate principle of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope.
