Description
Technical field
The present invention relates to a kind of antenna holder, relate in particular to a kind of assembly that is used for antenna holder.
Background technology
Because 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 use the antenna of different types to carry out electromagnetic measurement.Just because of the difference of antenna pattern, the above measurement antenna of present commercially available 1GHz nearly all is 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 height leading edge and is about on 80 centimetres the test platform 11, and 1 of antenna holder places from test platform 11 about 300 centimetres (about 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 between about 100～400 centimetres differing heights device 12 to be measured is measured.And then be elevated to overhead about 400 centimeters device 12 to be measured is measured.Because the design relation of 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 about 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 the measurement.
In order to improve above-described shortcoming, at present existing how tame manufacturer develops can be when antenna rises, the wide antenna holder 1 (Boresight Antenna Tower) that can always contain device 12 to be measured of the wave beam of antenna.Fig. 2 shows that promptly 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 more be changed and causes waste.Keep old antenna holder and only replace and have the part that always to aim at device 12 to be measured if want to save cost, so since the isolating door major part in the very huge and general indoor test place of antenna holder all opening is very little, be not enough to allow antenna holder pass in and out smoothly, so usually replace if desired, will certainly waste a lot of time and manpowers that move.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 the horizontal checkout of device 12 to be measured distance (as shown in Figure 2 apart from d) more and more far away gradually apart from meeting, and this kind shortcoming will have influence on the accuracy of test.
Consider the various shortcoming of above existing antenna holder, but industry presses for the scheme of the traditional antenna frame that a kind of antenna holder function that can be able to always to aim at device to be measured just buys before can not wasting, the measuring distance that not only can guarantee antenna and device to be measured is constant, but also can be installed in very fast on the old antenna holder of different factory plate models.
Summary of the invention
For the accuracy guaranteeing to measure and the increase property applied flexibly with reduce cost, the present invention discloses a kind of assembly that is used for antenna holder, its the horizontal survey distance that not only can guarantee antenna and device to be measured is constant, can make antenna aim at the accuracy of device to be measured again always, but also can be installed in very fast on the old antenna holder of different factory plate models to save set-up time and cost to guarantee to measure.
