Description
Technical field
The present invention relates to a kind of antenna holder, relate in particular to a kind of assembly for antenna holder.
Background technology
Due to making rapid progress of science and technology, the speed of service of electronic product is more and more faster, so that the operating frequency of product newly developed is more and more higher, therefore must carry out electromagnetic measurement with the antenna of different types.Just because of the difference of antenna pattern, the above measurement antenna of present commercially available 1GHz is nearly all to use horn antenna (Horn Antenna).
Fig. 1 shows with the electromagnetic schematic diagram of traditional antenna measurement, and device 12 to be measured is placed on the test platform 11 that the height leading edge is about 80 centimetres, and 1 of antenna holder is placed in from approximately 300 centimetres of test platforms 11 (approximately 350 centimetres away from test platform 11 centers be) and locates.The antenna tool 14 that is loaded with antenna on the vertical mast 13 of antenna holder 1 at first with overhead approximately between 100～400 centimetres differing heights device 12 to be measured is measured.And then be elevated to overhead approximately 400 centimeters device 12 to be measured is measured.Design relation due to horn antenna, the measurable wave beam of antenna is wide limited, so that when carrying out electromagnetic wave test, when antenna rises to high height (as overhead approximately 400 centimetres), the wave beam measured of horn antenna is wide can not contain device 12 to be measured fully, may just have the dead angle of measurement thus, cause the erroneous judgement in measurement.
In order to improve above-described shortcoming, at present existing many manufacturers develop can be when antenna rises, the wide antenna holder 1 that can always contain device 12 to be measured of the wave beam of antenna.Fig. 2 shows that namely this kind can aim at the schematic diagram of the antenna holder 1 of device 12 to be measured always, but the complex structure of this kind antenna holder 1, and cost is compared with the traditional antenna frame that used in the past, and price is high, and the antenna holder of old test site must replace and causes waste.If want to save cost, keep old antenna holder and only replace and have the part that can always aim at device 12 to be measured, all opening is very little for the isolating door major part in very huge due to antenna holder so and general indoor test place, be not enough to allow antenna holder pass in and out smoothly, if, so need to usually replace, will certainly waste time and the manpower of a lot of movements.In addition, another shortcoming is exactly when the antenna of this pattern rises, the floor projection of antenna and device to be measured 12 allows along with antenna height apart from meeting gradually apart from the horizontal checkout of device 12 to be measured distance (as shown in Figure 2 apart from d) more and more far away, and this kind shortcoming will have influence on the accuracy of test.
Consider the various shortcoming of above existing antenna holder, but the scheme of the traditional antenna frame that industry is just bought before can not wasting in the urgent need to a kind of antenna holder function that can be able to aim at device to be measured always, the measuring distance that not only can guarantee antenna and device to be measured is constant, but also can be arranged on very fast on the old antenna holder of different factory plate models.
Summary of the invention
For guaranteeing the accuracy of measuring and the increase property applied flexibly and reducing costs, the present invention discloses a kind of assembly for antenna holder, its the horizontal survey distance that not only can guarantee antenna and device to be measured is constant, can make again antenna aim at device to be measured to guarantee the accuracy of measuring always, but also can be arranged on very fast on the old antenna holder of different factory plate models to save set-up time and cost.
