Rfid system is widely used in logistics, production safety, road aspect at present.Special environment for use proposes more harsh requirement to rfid system, as: the aspects such as transmission range, coverage, oriented cover.Existing RFID antenna, in when design, could not take into full account practical application, and Antenna Design fails to select correct base material, design concept unintelligible, thereby cause RFID antenna, transmission range is short in use, coverage is little.
Utility model content
The purpose of this utility model is to solve the problem that current RFID antenna transmission distance is short, coverage is little, and a kind of RFID antenna is provided, and this RFID antenna gain is high, be with roomy, wide coverage, in whole working frequency range 862-928MHz, index is stable, product structure is simple, is easy to install.
For achieving the above object, the technical scheme that the utility model provides is as follows:
The RFID antenna that the utility model provides comprises radome, base plate, oscillator, ground strip, cable, coupling sheet, joint and support column; Radome is a hollow box body, comprise lower cover, upper outlet body, be parallel to each other and first end cap and second end cap vertical with upper lower cover, the first end cap and the second end cap are arranged on respectively the two ends of lower cover and upper outlet body, and the centre position of the first end cap is provided with through hole; Base plate and oscillator are tabular and are arranged in radome, and base plate is fixed on the inner side of lower cover, and base plate is parallel with oscillator, and connect by support column; Cable is fixed on base plate one end near the first end cap by ground strip, and cable is through through hole, and coupling sheet and joint have been installed respectively in the two ends of cable, and coupling sheet is between base plate and oscillator.
Especially, the material of described base plate and described oscillator is aluminium.
Especially, described base plate is rectangle, and on the axis of base plate, is provided with spacing hole, and described support column is through this spacing hole.
Especially, described oscillator is rectangle, and a triangle is all removed by sanction in four angles, on the axis of oscillator, is provided with location hole, and described support column is through this location hole.
Especially, described support column is fixedly connected with described base plate and described oscillator.
Especially, the both sides of described lower cover are provided with groove, and the both sides of described upper outlet body are provided with the projection suitable with this groove, and lower cover and upper outlet body snap together by groove and projection.
Especially, described the first end cap and the second end cap are provided with the boss of a convex shape, and this boss embeds between described lower cover and upper outlet body.
Especially, described coupling sheet is L font.
The beneficial effects of the utility model: the radome of the RFID antenna that the utility model provides is split as lower cover, upper outlet body, the first end cap and the second end cap, be convenient to install other members of RFID antenna in this radome, and lower cover and upper outlet body fasten mutually, the first end cap and the second end cap embed between lower cover and upper outlet body, lower cover, upper outlet body, the first end cap and the second end cap in conjunction with closely, can reach IP65 dustproof and waterproof grade each other; Oscillator is rectangle, and a triangle is all removed by sanction in four angles, and according to facts have proved, the RFID antenna footprint that the utility model provides is wide, gains high in whole working frequency range, is with roomy.
