Abstract
The utility model relates to a low profile antenna unit which the two sides are flanged, belonging to the field of tabulate aerial technology, and comprising a radiant panel(1), a short circuit pillar(2), a feed pillar(3), a medium support(6) and a baffle-board(7); wherein the radiant panel(1) and the baffle-board(7) are arranged parallelly in interval through the short circuit pillar(2) and the feed pillar(3); the utility model is characterized in that flanges(8) are both arranged at the two sides of the radiant panel(1), and the distance between the radiant panel(1) and the baffle-board(7) is between 8 to 11 mm. the utility model has eth advantages of solving the problem that the prior low profile antenna unit has not enough isolation between the array elements and weak front-to-rear, thereby incapably satisfying the design requirement of the array; in addition, the utility model also has the advantages of simple structure, convenient making and good isolation.
Description
Technical field
The utility model relates to a kind of low profile antenna unit, especially a kind of TD-SCDMA smart antenna unit, specifically a kind of low profile antenna unit of two side flangings.
Background technology
At present, the isolation that common element antenna generally shows between the array element in the array of TD-SCDMA smart antenna is not enough, and front and back are poor, can't satisfy the demand of array design, and processing cost, cycle can't be satisfied requirement of mass production simultaneously.Exploitation and index optimization to intelligent antenna array have produced very big influence, have restricted carrying out of system algorithm research work.
Summary of the invention
The purpose of this utility model is not enough at the isolation between the array element of existing low profile antenna unit existence, front and back are poor, can't satisfy the problem of array design demand, provide a kind of simple in structure, easily manufactured, isolation is the low profile antenna unit of two side flangings preferably.
The technical solution of the utility model is:
A kind of low profile antenna unit of two side flangings, comprise radiant panel 1, short circuit pillar 2, feed pillar 3, locking nut 4, locking nut 5, dielectric support 6, reflecting plate 7, radiant panel 1 and reflecting plate 7 are installed by short circuit pillar 2 and feed pillar 3 spaced and parallel, one end of short circuit pillar 2 links to each other with reflecting plate 7, its other end passes radiant panel 1 and links to each other with radiant panel 1 by locking nut 5, one end of feed pillar 3 is fixed on the reflecting plate 7 by dielectric support 6, its other end also passes radiant panel 1 and links to each other with radiant panel 1 by locking nut 4, the both sides that it is characterized in that radiant panel 1 are equipped with flange 8, and the distance between radiant panel 1 and the reflecting plate 7 is between 8～11mm.
The height of described flange 8 is 4mm～6mm, and its direction is upwards upset.
Described radiant panel 1 is a metal aluminum sheet
There is flange the both sides of radiant panel 1, radiant panel 1 is closer from the distance of reflecting surface, adopt short circuit pillar 2 to realize the stable installation of radiator, feed pillar 3 is transferred to the back side with distributing point, utilizes dielectric support 6 to guarantee that the spacing between distributing point and the base plate is the substantive distinguishing features that the utility model is different from prior art.
The beneficial effects of the utility model:
1, the utility model adopts the metal manufacturing, and is simple in structure, is very easy to be guaranteed at aspects such as processing, assembling consistency, and batch product is had very great help.
2, the isolation between the unit improves a lot compared with similar products.
3, both sides adopt the turnup structure standing wave little, and debugging work load is little.
Description of drawings
Fig. 1 is a side-looking structural representation of the present utility model.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, 2.
A kind of low profile antenna unit of two side flangings, comprise metal radiant panel 1, short circuit pillar 2, feed pillar 3, locking nut 4, locking nut 5, dielectric support 6, reflecting plate 7, as shown in Figure 1, radiant panel 1 can adopt the aluminium sheet bending about 1mm to make or draw section bar, its both sides are equipped with flange 8, the height right side of flange is 4～6mm, dielectric support 6 adopts nylon or plastic injection piece, and being designed to bayonet socket spare version, its effect is the concentric circles relation that is used to locate between feed pillar 3 and the reflecting plate power feed hole; Radiant panel 1 and reflecting plate 7 are realized the spaced and parallel installation by short circuit pillar 2 and feed pillar 3, one end of short circuit pillar 2 links to each other with reflecting plate 7, its other end passes radiant panel 1 and links to each other (as shown in Figure 2) with radiant panel 1 by locking nut 5, both can guarantee the mounting structure size of unit, also can realize the lightning protection function of DC earthing.One end of feed pillar 3 is fixed on the reflecting plate 7 by dielectric support 6, and its other end also passes radiant panel 1 and links to each other with radiant panel 1 by locking nut 4, and the distance between radiant panel 1 and the reflecting plate 7 is between 8～11mm.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
