Abstract
The utility model discloses a medium support for fixing the air microstrip line. The medium support is fabricated by the plastic with easy forming, low dielectric constant, and low wastage, compising a fixed part and a holding part. The fixed part is in a columnar shape with through holes, and the cylinder is optimized. The holding part is extended from the fixed part, and the holding part is composed of an upper part used to press the air microstrip line, and a lower part used to partition the air microstrip line and the ground plate. An opening used to hold the air microstrip line is formed between the upper part and the lower part, and the width of the opening is corresponding to the thickness of the air microstrip line. In order to keeping the hold stable and reliable and reducing the effect of the electromagnetic field between the microstrip line and the ground plate, that the extension of the upper part is longer than the extension of the lower part, the volume of the upper part is bigger than the volume of the lower part is optimized, and a discharge spout is arranged on the bottom of the medium support. The utility model has the advantages of smaller volume, assembly space saving, low cost, better effect of the fixed microstrip line, simple assembly, and assembly completing by using the pneumatic hitter.
Description
Technical field
The utility model relates to the antenna of mobile communication base station field, relates in particular to a kind of air microstrip line with antenna for base station inside and is fixed on dielectric support on the antenna ground plate.
Background technology
Along with developing rapidly of mobile communication, the antenna that is applied to the mobile communication base station has also been proposed more and more higher requirement, plate antenna is a kind of antenna commonly used.To have loss little because of it for the antenna that adopts the air microstrip feed, passive intermodulation index is good, production cost is low, power capacity is big, is easy to advantages such as production in enormous quantities, is widely used day by day, and for the consideration to cost and processing technology, the microstrip line thickness of generally selecting for use is all less, and as 1-2 millimeter, at this moment the characterisitic parameter of microstrip transmission line is only relevant with the width W of the height H of microstrip line and microstrip line.If height H obtains too smallly, then the coupling between air microstrip line and the ground plate can increase, and makes the thickness of microstrip line become and can not ignore; If the radiation meeting of the excessive then air microstrip of the height H value line of microstrip line increases accordingly, thereby cause the signal increase that in transmission course, decays, so the spacing of microstrip line of generally selecting for use and ground plate is the 2-5 millimeter.But simulation result shows, small variation takes place in the spacing of microstrip line and ground plate, its electric property all can have significant change, so, in production and debug process, how to make air microstrip traditional thread binding join simple effectively, and can keep good stable become the urgent problem that microstrip line is installed in use from now on.
The way that generally adopts is to make a call to an aperture about φ 3mm on the microstrip line, fixing with working of plastics then at present.One of common method is that the mode with working of plastics simulation swell fixture fixes microstrip line.But because microstrip line is narrow, so the strong point substantially point-blank, so just make the network run-off the straight easily, influence its electrical property, in addition, in order to keep the distance between microstrip line and the ground plate, it must be put the glue of screw thread glue or silica gel and so on and prevent that the system working of plastics gets loose, and consequently wastes time and energy; Another method adopts shape as " fourth " font working of plastics exactly, and aperture is passed at an angle, and two other angle is fixed on the ground plate, does the defective that has effectively overcome first method like this, but its defective is the distance that can not guarantee microstrip line and ground plate.The way that also has is with heating tools such as flatirons the air microstrip strutting piece to be scalded riveting, but accuracy and little, and from environmental angle, boiling hot riveting also brings environmental pollution easily.
The utility model content
Problem to be solved in the utility model is in order to solve the problem of the dielectric support assembling inconvenience, reliability and the poor accuracy that are used for fixing the air microstrip network in the prior art, and a kind of easy to assembly, dielectric support that is used for fixing the air microstrip line that reliability is high is provided.
The technical scheme that the utility model adopted is: the dielectric support that is used for fixing the air microstrip line is selected easy machine-shaping and low-k for use, low-loss plastics are made, comprise standing part and retained part, standing part is the cylinder of a band through hole, cylinder is preferably cylinder, retained part stretches out from standing part, retained part comprises in order to the top of pushing down the air microstrip line with in order to separate the bottom of air microstrip line and ground plate, form the opening in order to clamping air microstrip line between the upper and lower, the thickness of the width of opening and air microstrip line adapts.Reliable and stable and reduce influence for clamping to electromagnetic field between microstrip line and the ground plate, be preferably top than the bottom stretch out long, volume is big.The dielectric support bottom that is used for fixing the air microstrip line also can be provided with a sluicing groove, can reduce the influence to electric property on the one hand, and the condensed water of generation is flowed away smoothly, is short-circuited around avoiding accumulating in.
The beneficial effects of the utility model are: the one, and volume is less, can utilize the gap of air microstrip network itself to assemble, and has saved assembly space.The 2nd, compared with prior art, the utility model fixedly effect of microstrip line is better, after debugging is finished, in transit or in use, the electric property of antenna can not change.And the utility model assembling is simple, and cost is low, uses pneumatic riveting gun can finish assembling.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is an embodiment contour structures schematic diagram of the present utility model;
Fig. 2 is embodiment installation steps one schematic diagram of the present utility model;

Embodiment
As shown in Figure 1, the utility model is selected easy machine-shaping and low-k for use, low-loss plastics are made, comprise standing part and retained part, standing part is the cylinder 5 of a band through hole, in order to the staking retaining clip, retained part stretches out from standing part, retained part comprises in order to push down stretching out of air microstrip line longer, the top 1 that volume is bigger and shorter in order to separate stretching out of air microstrip line and ground plate, the bottom 2 that volume is less, form the opening 4 in order to clamping air microstrip line between top 1 and the bottom 2, the thickness of the width of opening 4 and air microstrip line adapts.The dielectric support bottom also is provided with a square sluicing groove 3, works to drain condensed water.
Fig. 2, Fig. 3 and Fig. 4 as shown in Figure 2, at first are inserted into rivet 6 in the preformed hole of dielectric support standing part for utilizing rivet that dielectric support is fixing with to the passive process schematic diagram of feeding network; Then, as shown in Figure 3, rivet 6 and dielectric support are inserted in the preformed hole of ground plate 7, and guarantee that the opening 4 of dielectric support faces microstrip line 8; At last, as shown in Figure 4, after the staking, air microstrip line 8 is fixed on the ground plate 7 firmly.
