Abstract
The utility model provides a kind of good directional aerial of heat dissipation performance, including panel and shell, the panel and shell surround cavity, reflecting plate is equipped in the cavity, the feed line of the radiating element and electrical connection radiating element that are mounted on reflecting plate, the reflecting plate is set as plane towards radiating element on one side, another side is equipped with cooling fin, in directional aerial work, the heat that radiating element 3 generates reaches on cooling fin through reflecting plate, since the surface area of cooling fin is larger for plane, therefore rapidly heat diffusion can be come out, to make the reduction of radiating element temperature.
Description
Technical field
The utility model relates to domain of communication equipment, in particular to a kind of good directional aerial of heat dissipation performance.
Background technique
Directional aerial refers to be emitted and to receive electromagnetic wave especially strong on some or certain several specific directions, and at other
Direction on emit and receive electromagnetic wave be zero or a kind of minimum antenna.Directional aerial when in use, need to constantly receive and dispatch electricity
Magnetic wave, therefore its radiating element temperature for being used for transceiving electromagnetic wave can increase, and will lead under radiating element performance if temperature is excessively high
Drop, therefore radiator need to be set to directional aerial, existing directional aerial is all that radiator is arranged outside antenna case, in this way
Not only make antenna structure complicated, heat dissipation effect is ideal not enough.
Utility model content
The ideal directional aerial of simple and heat dissipation effect the technical problem to be solved by the present invention is to provide a kind of structure.
In order to solve the above-mentioned technical problem, the utility model provides a kind of good directional aerial of heat dissipation performance, including face
Plate and shell, the panel and shell surround cavity, and reflecting plate, the radiating element being mounted on reflecting plate are equipped in the cavity
With the feed line of electrical connection radiating element, the reflecting plate is set as plane towards radiating element on one side, and another side is equipped with heat dissipation
Piece, the back side of the shell offer notch and are pierced by for cooling fin.
Preferably, the edge of the shell is made of metal material.
Preferably, the metal material is aluminium.
Preferably, the panel is made of nonmetallic materials.
Preferably, the nonmetallic materials are polypropylene plastic.
Preferably, the reflecting plate is aluminium sheet.
The utility model has the following beneficial effects: the heat that radiating element 3 generates is through reflecting in directional aerial work
Plate reaches on cooling fin, since the surface area of cooling fin is larger for plane, can rapidly go out heat diffusion
Come, to make the reduction of radiating element temperature.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of directional aerial；
Fig. 2 is that directional aerial removes the structural schematic diagram after panel；
Fig. 3 is the structure schematic diagram of directional aerial；
Fig. 4 is the structural schematic diagram of reflecting plate.
Description of symbols: 1- shell；2- reflecting plate；3- radiating element；4- feed line；5- panel；6- cooling fin.
Specific embodiment
Directional aerial is as shown in Figure 1, include shell 1 and panel 5,5 panel 5 of panel is made of nonmetallic, general to use
Polypropylene plastic (PP plastic cement), to not interfere with electromagnetic wave while guaranteeing that panel 5 protects inner antenna part
Propagation.As shown in Fig. 2, being equipped with reflecting plate 2 in the cavity that shell 1 and panel 5 surround, reflecting plate 2 is aluminium sheet, is fixed with thereon
Radiating element 3,4 one end of feed line are electrically connected radiating element 3, and the other end connects front end system (not shown).Radiating element 3
It is transferred to front end system by the signal that feed line 4 receives antenna, the signal of front end system output is transmitted by feed line 4
It is radiated the external world in the form of an electromagnetic wave to radiating element 3, then by radiating element 3, the electromagnetic wave letter that radiating element 3 radiates
It number after the surface reflection of reflecting plate 2, radiates towards specific direction, the orientation of electromagnetic wave is conveyed to realize.Shell 1
Edge is made of metallic aluminium, so that the bottom surface and side of radiating element 3 are all surrounded by metal, what radiating element 3 radiated
Electromagnetic wave directional properties are more preferable.
As shown in figure 4, reflecting plate 2 is set as plane on one side, another side is equipped with multiple cooling fins 6.The back of shell as shown in Figure 3
Face offers notch and is pierced by for cooling fin 6, and when reflecting plate 2 is mounted on directional aerial, plane is equipped with towards radiating element 3
The one of cooling fin 6 passes through the notch on shell 1 facing towards shell 1, cooling fin, and the cooling fin 6 in Fig. 2 on reflecting plate 2 is because of angle
Degree problem is blocked.In directional aerial work, the heat that radiating element 3 generates reaches on cooling fin 6 through reflecting plate 2, by
It is larger for plane in the surface area of cooling fin 6, therefore can rapidly come out heat diffusion, to make radiating element
3 temperature reduce.
