Description
Technical field
The present invention relates to antenna measurement fields, and in particular to is suitable for the equipment of near field antenna test.
Background technology
The fast development of communication has pushed the R＆D work of antenna, thus occur some produce per year antennas reach tens of thousands of,
Kind reaches hundreds of enterprises.The speed of antenna measurement nowadays has become the bottleneck of Corporation R ＆ D work.Far-field measurement method,
Although directional diagram can be measured directly, larger measuring distance is often required that, test speed is too slow, is only capable of surveying solid side every time
To a section, information content is very little, it is possible to omit some important information.Near-field measurement technique represents antenna measurement skill
The developing direction of art.The advantages of such technology, is：Required place is small, and high-precision survey can be carried out in microwave dark room
Amount eliminates the difficulty for building large-scale microwave dark room.Near-field measurement technique checkout area is affected by the surrounding environment small, guarantee whole day
The measurement work of antenna can be smoothed out by waiting.
In the prior art, antenna measurement equipment realizes the fixation to antenna by pole, but uses this kind of mode, armful
Bar can impact antenna scanning.
Invention content
Present invention aims at the equipment for being suitable near field antenna test is provided, solves antenna measurement equipment and pass through pole reality
Now to the fixation of antenna, but this kind of mode is used, the problem of pole can impact antenna scanning.
The present invention is achieved through the following technical solutions：
Suitable for the equipment of near field antenna test, including antenna to be measured, the antenna to be measured is vertically arranged, described to wait for observation
The lower end of line is provided with tumbler, and the tumbler includes device of rotation driving, the rotation being connect with device of rotation driving
Axis, the support plate for being fixed on shaft upper end are also fixedly connected with L-type connecting rod, one end of the L-type connecting rod in the shaft
It is connected with grip block, the grip block is located at the upper end of antenna to be measured.
Further, it is suitable for the equipment of near field antenna test, one end of the L-type connecting rod is provided with sliding groove, institute
It states sliding groove and is connected with sliding block, the grip block is connect with sliding block, and finite place piece is arranged in the L-type connecting rod.
Further, it is suitable for the equipment of near field antenna test, the locating part is connect by anchor ear with L-type connecting rod.
Further, it is suitable for the equipment of near field antenna test, the lower surface of the grip block is provided with buffer layer.
Compared with prior art, the present invention having the following advantages and advantages：
Inventive antenna is vertically-mounted, antenna is fixed with turntable using grip block so that the directional diagram of antenna
Main lobe and secondary lobe are directed toward the horizontal direction in darkroom, to avoid turntable for the influence of ratio before and after antenna；It is simple in structure, it fixes more
It is convenient.
Specific implementation mode
To make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiment, the present invention is made
Further to be described in detail, exemplary embodiment of the invention and its explanation are only used for explaining the present invention, are not intended as to this
The restriction of invention.
Embodiment 1
The equipment that the present embodiment is suitable near field antenna test, including antenna to be measured, the antenna to be measured are vertically arranged, institute
The lower end for stating antenna to be measured is provided with tumbler, and the tumbler includes device of rotation driving, connects with device of rotation driving
The rotation axis that connects, the support plate for being fixed on shaft upper end are also fixedly connected with L-type connecting rod, the L-type connection in the shaft
One end of bar is connected with grip block, and the grip block is located at the upper end of antenna to be measured.
The present invention treats observation line with turntable application by grip block and is fixed, and antenna to be measured is located at vertical direction, turns
It drives grip block same direction to be rotated when dynamic device is rotated, is easy to implement the scanning to antenna.
Embodiment 2
On the basis of embodiment 1, one end of the L-type connecting rod is provided with sliding groove, and the sliding groove is connected with
Sliding block, the grip block are connect with sliding block, and finite place piece is arranged in the L-type connecting rod.The locating part passes through anchor ear and L-type
Connecting rod connects.Convenient for adjusting the height of grip block, using from the antenna to be measured of different more height, and by locating part to sliding block
Position be defined.Locating part is two convex blocks, is separately positioned on the upper and lower of sliding block, and pass through anchor ear and L-type connecting rod
Connection makes two limited blocks be fastenedly connected with L-type connecting rod when grip block arrival position appropriate by adjusting anchor ear, sliding
Block is limited between two limited blocks so that the distance between grip block and tumbler be fixed to be treated observation line and pressed from both sides
It holds.
Embodiment 3
On the basis of embodiment 1, the lower surface of the grip block is provided with buffer layer.
Above-described specific implementation mode has carried out further the purpose of the present invention, technical solution and advantageous effect
It is described in detail, it should be understood that the foregoing is merely the specific implementation mode of the present invention, is not intended to limit the present invention
Protection domain, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should all include
Within protection scope of the present invention.
