Background technology
Along with the fast development in the communication technology and field, promote the R&D work of antenna, domesticly occur that some produce antennas per year and reach millions of, kind and reach the enterprise more than hundreds of.The speed of antenna measurement has become Corporation R & D work " bottleneck ".Far field method of testing, although can directly measure directional diagram, usually requires larger measuring distance, and test speed is too slow, and the quantity of information of obtaining is few.Near-field measurement technique is representing the developing direction of antenna measurement technology.The major advantage of this technology is: required place is little, can in microwave dark room, carry out high-precision measurement; Near field technique test is simultaneously subject to the impact of surrounding environment minimum, and guarantee whole day can be carried out the test of antenna smoothly; And the quantity of information that can obtain is larger.Traditional near field measurement equipment is single probe type, and test speed is very slow, and multi-probe near-field measurement system is a major reform of near-field measurement technique.
Summary of the invention
In order to realize the object of obtaining compared with large information capacity and raising test speed, the utility model provides a kind of and can obtain compared with large information capacity, 16 fast probe near field antenna test macros of test speed.
It is as described below that the utility model solves the technical scheme that its technical matters adopts: a kind of 16 probe near field antenna test macros, it is characterized in that, comprise vector network analyzer, active switch unit, radiocommunication test instrument, the amplifying unit that data acquisition is connected with processing computer with data acquisition with processing computer, respectively and the 16 probe near field antenna testing apparatuss that are connected with amplifying unit.
Described 16 probe near field antenna testing apparatuss comprise bracing frame, it is bad that bracing frame both sides are provided with metal, in becket, the ring left and right sides is provided with taper suction ripple cotton, arranges to put and see probe apparatus on the cotton adapter ring of both sides taper suction ripple, and on probe apparatus, cover is seen U-shaped protection suction ripple cotton.Support frame as described above below is provided with strap brake castor.
Support frame as described above is provided with handle.
According to the utility model of said structure, its beneficial effect is, the utility model can obtain fast compared with large information capacity, test speed, and saves space.
Brief description of the drawings
Below in conjunction with accompanying drawing and embodiment, the utility model is described further.
Fig. 1 is the utility model system construction drawing;
Fig. 2 is the structural drawing of the utility model 16 probe near field antenna testing apparatuss.
Embodiment
As shown in Figure 1, 2, a kind of 16 probe near field antenna test macros, comprise vector network analyzer, active switch unit, radiocommunication test instrument, the amplifying unit that data acquisition is connected with processing computer with data acquisition with processing computer, respectively and the 16 probe near field antenna testing apparatuss that are connected with amplifying unit.Described 16 probe near field antenna testing apparatuss comprise bracing frame 3, bracing frame 3 both sides are provided with becket 1, the interior ring of becket 1 left and right sides is provided with taper and inhales ripple cotton 7, and both sides taper is inhaled on cotton 7 adapter rings of ripple and arranged and be provided with probe apparatus 6, is overlapping U-shaped protection and inhale ripple cotton 5 on probe apparatus.Support frame as described above 1 below is provided with strap brake castor 4.Support frame as described above 1 is provided with handle 2.
16 probe near field antenna test macros are used for limited space, cost control, and the laboratory that requires test macro easily to move flexibly, workshop etc.The antenna array of 16 probes can provide test at a high speed and the accurate test result of antiradar reflectivity.Wheel is arranged at 16 probe near field antenna testing apparatus bottoms, and small volume, can pass through the two-door of standard, and one of them suction ripple cylinder can be dismantled, to pass through standard simple gate.For the non-source test of antenna, 16 probe near field antenna testing apparatuss need be connected with a network analyzer; For active test, be generally the OTA effect test of mobile phone or other mobile phones, need 16 probe near field antenna testing apparatuss to be connected with a radio communication tester, and lay a mobile phone in many probes gust central authorities of 16 probe near field antenna testing apparatuss, test complete machine is in emissive power and the receiving sensitivity of three dimensions all directions.16 probe near field antenna testing apparatuss based on the 16 probe near field antenna test macros gust patented technology of popping one's head in more, be different from traditional single probe mechanical scanning, 16 probe near field antenna testing apparatuss adopt the electron scanning of 16 probe battle arrays, only need measured object to do 180 ° of azimuthal machinery rotations, can carry out the test of complete spheroid face.Compared with traditional single probe test macro, comprehensively three-dimensional test means test speed faster.For small size antenna, the space samples of 22.5 ° is enough to annotate accurately antenna pattern, and for the large-scale antenna of the better sampled data of needs, the pattern that 16 probe near field antenna testing apparatuss provide unique electron scanning and mechanical scanning to combine, probe battle array can rotate ± and 11.25 °, this locating bias can fill probe between azimuthal deviation, can not limit sampling.Vertical mechanical scanning combines with the electron scanning of 16 probes, means that at a high speed comprehensively full-automatic test system all scans not limited at vertical and position angle.For radiosensitivity test and other tests that perplexed by external disturbance of mobile phone, 16 probe near field antenna test macros provide a supporting small-sized screened room, and this screened room can be loaded onto taper and inhale ripple sponge on two face walls in the face of inhaling the opening part that ripple is flexible.
