Description
Technical field
The utility model relates to directional antenna technique field, the directionality of specifically a kind of X-band directional aerial is surveyed
Try frame.
Background technique
What the directionality of antenna indicated is antenna in all directions for the radiation of signal and reception ability, is antenna performance
One of important indicator.
In radio frequency microwave system, the index of the directionality in relation to antenna is often tested, this is in place for the institute of antenna
More accurate positioning will be had by setting.Especially for the signal of X-band (8-12GHz), since wavelength is shorter (3 centimetres or so), day
The size of line is inherently smaller, and a small amount of location error will cause test error.On the other hand, it for directional aerial, closes
The heart is antenna square upwardly direction index, is not needed traditionally, and antenna is placed on 360 degree of complete cycles of progress on turntable
Test.
General such antenna measurement frame is mainly characterized by：1, platform not can be carried out and accurately move, for X-band day
The directionality test of line is inaccurate；2, depend on turntable usually to realize, in practice It is not necessary to, but bring volume it is big, at
This height is not easy the disadvantages of disposing.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, for X-band directional aerial, design
The X-band directional aerial directionality testing jig of a kind of simplicity out, can be precisely located aerial position, to improve the directionality of antenna
Test process.
Technical solution used by the utility model：
A kind of directionality testing jig of X-band directional aerial, including ball screw, driving stepper motor, stepper motor drive
The fixed slide unit of movable plate, antenna, laser generator and antenna to be measured, the driving stepper motor are mounted on ball screw side, institute
It states driving stepper motor and ball screw drive shaft matches, the driving stepper motor side is equipped with stepper motor driving plate；
The fixed slide unit of the antenna is installed on ball screw, and the antenna to be measured is mounted on the fixed slide unit of antenna, and the laser produces
Raw device is mounted on immediately below antenna to be measured.
Preferably, the lead of the ball screw is less than 5mm, i.e., one circle of driving stepper motor rotation, antenna are fixed
Slide unit translation is less than 5mm.
A kind of X-band directional aerial directionality testing jig disclosed by the utility model, after adopting the above structure, in practical dress
Timing effect obtained has reached expected purpose, and accurate positioning, easy for installation, as follows：
1, screw rod, slide unit are driven using stepper motor, and the position of antenna can be made to be accurate in 5mm.
2, for directional aerial, traditional turntable is not used to test, and is tested using straight-bar slide unit, enormously simplify test
The structure of frame.
The utility model is described in further detail with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model X-band directional aerial directionality testing jig.
In figure, 1- ball screw 2- drives the fixed slide unit 5- laser of stepper motor 3- stepper motor driving plate 4- antenna
Generator 6- antenna to be measured.
Specific embodiment
In order to deepen the understanding to the utility model, the utility model is made with reference to the accompanying drawings and examples further detailed
Thin explanation.Following embodiment is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation limitation
The protection scope of the utility model.
As shown in Figure 1, a kind of directionality testing jig of X-band directional aerial, including ball screw 1, driving stepper motor
2, the fixed slide unit 4 of stepper motor driving plate 3, antenna, laser generator 5 and antenna to be measured 6, driving stepper motor 2 are mounted on rolling
1 side of ballscrew, driving stepper motor 2 and 1 drive shaft of ball screw match, and driving 2 side of stepper motor is equipped with stepping electricity
Machine driving plate 3；The fixed slide unit 4 of antenna is installed on ball screw 1, and antenna 6 to be measured is mounted on the fixed slide unit 4 of antenna, laser
Generator 5 is mounted on immediately below antenna 6 to be measured.
In the present embodiment, the lead of ball screw 1 is less than 5mm, i.e. one circle of driving stepper motor rotation, the fixed slide unit of antenna
Translation is less than 5mm.
The specific work process of the utility model：The rotation of ball screw 1 is driven using driving stepper motor 2, is driven
The mode of the fixed slide unit 4 of antenna allows the fixed slide unit 4 of antenna to carry out horizontal movement on ball screw 1, so that antenna to be measured
6 move horizontally precision and can become very high, also simplifies the structure of testing jig.
In the present embodiment, the velocity of rotation of driving stepper motor 2 depends on the pulse speed that stepper motor driving plate 3 generates
Degree, the pulse can be generated according to the needs of test equipment by mcu programming.
In the present embodiment, antenna 6 to be measured is mounted on the fixed slide unit 4 of antenna, and laser generator 5 is mounted on antenna 6 to be measured
The center position of antenna to be measured is found for being directed at test equipment in underface.
The directionality testing jig of X-band directional aerial shown in the utility model is lighter, is mainly used for such day
Test of the line in relation to directionality index.It can allow antenna to synchronize in the way of testing required by environment and accurately transport
Dynamic, cooperation test equipment measures the directivity plot of antenna.
It is noted that embodiment described above is the affiliated skill to the illustrative and not limiting of technical solutions of the utility model
The equivalent replacement of art field those of ordinary skill or other modifications made according to the prior art, as long as practical not new beyond this
The thinking and range of type technical solution, should be included within interest field required by the utility model.
