Abstract
The invention relates to a RFID reader-writer antenna, which pertains to the technical field of the design of RFID reader-writer antenna structure. Aiming at solving problems that the existing RFID low-frequency reader-writer has a short reading and writing distance, high power consumption and large copper loss, the design of the RFID reader-writer antenna of the invention comprises rectangular hollow coil antenna formed by enwinding two Phi 0.10mm-0.18mm diameter copper enamelled wires or aluminum enamelled wires in parallel and has two terminal ends, and two thrums of each terminal end are welded together, thus reducing the general diameter, the power consumption and copper loss, extending the reading and writing distance of the reader-writer and being most applicable to portable RFID reader-writer antennas with low frequency.
Description
Technical field
The present invention relates to a kind of rfid interrogator Antenna Design, belong to the antenna structure design field of rfid interrogator.
Background technology
Existing low frequency RF ID reading and writing device antenna all adopts a copper enamelled wire coiling to form coil antenna, in order to make the increase reading/writing distance, often adopts the thick copper enamelled wire in line footpath; Like this; Copper loss is big, and power consumption is also high, is unfavorable for the popularization of portable RF ID low frequency read write line.For example, turn to 45mmx62mm rectangle air core coil antenna with a Ф 0.25mm line footpath copper enamelled wire, inductance value 410uH, antenna internal resistance 4.1 Ω, low frequency rfid interrogator maximum is read apart from 7.3mm, low frequency rfid interrogator source current 190mA.
Summary of the invention
To the above-mentioned defective of prior art, the present invention will solve problems such as to be suitable for portable RF ID low frequency read write line coil antenna copper loss little, and power consumption is low, and the read write line reading/writing distance is long.
For solving above-mentioned technical problem of the prior art; The present invention provides a kind of rfid interrogator Antenna Design; Adopt two Ф 0.15mm line footpath parallel coilings of copper enamelled wire to form a 45mmx62mm rectangle hollow coil antenna; Two Ф 0.15mm line footpath copper enamelled wires are structurally parallel, and two terminations are arranged, and two the end of a thread of each termination weld together.The coil antenna inductance value 410uH of two Ф 0.15mm line footpath copper enamelled wire coilings, antenna internal resistance 5.7 Ω, low frequency rfid interrogator maximum is read apart from 9.3mm, low frequency rfid interrogator source current 144mA.
Among the present invention, also can be aluminium copper-clad enamelled wire through said copper enamelled wire;
Among the present invention, also can be circular hollow coil through said rectangle hollow coil;
Among the present invention, adopt the parallel coiling of self-adhesive enameled wire, also can adopt the coiling that walks abreast of non-self-adhesive enameled wire through the parallel coiling of said enamelled wire;
Among the present invention,, also can adopt the copper enamelled wire in line footpath between the Ф 0.11-0.18mm through the copper enamelled wire in said Ф 0.15mm line footpath;
The invention has the beneficial effects as follows that the line of RFID low frequency read write line coil antenna has directly reduced, copper loss is little, and power consumption is also low, and the read write line reading/writing distance is long, is suitable for portable RF ID low frequency read write line coil antenna most.
Description of drawings
To combine accompanying drawing and embodiment that the present invention is described further below, in the accompanying drawing:
Fig. 1 is the antenna structure view of a rfid interrogator of the present invention.
Wherein, 1 and 2 represent two the end of a thread of a termination respectively, and 3 and 4 represent two the end of a thread of another termination respectively.
Embodiment
In a preferred embodiment of the present invention; Adopt two Ф 0.15mm line footpath parallel coilings of copper enamelled wire to form a 45mmx62mm rectangle hollow coil antenna; Two Ф 0.15mm line footpath copper enamelled wires are structurally parallel, and two terminations are arranged, and two the end of a thread of each termination weld together.Promptly 1 and 2 two the end of a thread welds together, and 3 and 4 two the end of a thread weld together.The coil antenna inductance value 410uH of two Ф 0.15mm line footpath copper enamelled wire coilings, antenna internal resistance 5.7 Ω, low frequency rfid interrogator maximum is read apart from 9.3mm, low frequency rfid interrogator source current 144mA.
To describe the characteristics of a kind of rfid interrogator Antenna Design of present embodiment below in detail.
1, said copper enamelled wire also can be an aluminium copper-clad enamelled wire.Can realize also that with the coil antenna of aluminium copper-clad enamelled wire coiling copper loss is little, power consumption is also low, and the read write line reading/writing distance is long etc.
2, said rectangle hollow coil also can be circular hollow coil.Circular hollow coil antenna can realize that also copper loss is little, and power consumption is also low, and the read write line reading/writing distance is long etc.
3, the parallel coiling of self-adhesive enameled wire is adopted in the parallel coiling of said enamelled wire, also can adopt the coiling that walks abreast of non-self-adhesive enameled wire.Adopt the parallel coiling of non-self-adhesive enameled wire can realize that also copper loss is little, power consumption is also low, and the read write line reading/writing distance is long etc.
4, said Ф 0.15mm line footpath copper enamelled wire also can adopt the copper enamelled wire in line footpath between the Ф 0.11-0.18mm.Adopt the copper enamelled wire in line footpath between the Ф 0.11-0.18mm can realize that also copper loss is little, power consumption is also low, and the read write line reading/writing distance is long etc.
Adopt RFID low frequency read write line coil antenna of the present invention, line has directly reduced, and copper loss is little, and power consumption is also low, and the read write line reading/writing distance is long, especially is suitable for portable RF ID low frequency read write line coil antenna.
