Additionally, traditional antenna design is usually and is placed on mainboard or the heat sink of wireless device by antenna, other element making antenna and wireless device is arranged in pairs or groups, thus utilize main board system ground plane as a part for antenna, its design is mainly: ironware antenna is designed to Dip pattern, will downwardly extend out Dip pin by antenna body, this Dip pin is inserted in mainboard or heat sink, thus enables the antenna to good radiation.
Above-mentioned Antenna Design mode need to share with the ground plane of main board system, the board of wireless device there is higher dependency, it is used in varying environment the biggest on the impact of traditional antenna, therefore find a mechanism and reduce the influence degree etc. between antenna and the annoyance level of environment, antenna, reform into an important topic.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, it is provided that a kind of antenna, its radiation pattern with high directivity and antenna performance the most affected by environment.
To achieve these goals, this utility model provides a kind of antenna, and it is in AP and Set Top Box wireless device, and described antenna includes earth plate and the antenna body being made up of sheet metal integrated punching；Described earth plate removably assembles and is fixed on wireless device；Described antenna body is an inverted L-shaped, and it has a plate and a radiant panel, and connecting plate is vertically connected with earth plate, and radiant panel is spaced and parallel with earth plate relative.
As further improving, the connecting plate of described antenna body vertically bends extension and is formed from an outward flange of earth plate.
As further improving, the middle part of described earth plate offers a rectangular window, and the connecting plate of described antenna body vertically bends extension and formed from an inward flange of the window of earth plate, and the radiant panel of antenna body is relative with window.
As further improving, described antenna has a welded plate further, and welded plate bends to extend towards earth plate from the ending vertical of the radiant panel of antenna body and forms, and welded plate is spaced and parallel with connecting plate is oppositely arranged.
As further improving, described earth plate offers several spaced screw hole.
In sum, the antenna that this utility model provides is freestanding antenna, itself has earth plate, and the element being not required to be applied on wireless device board at design aspect just can have good radiation, therefore it is less susceptible to the environmental effect by board, also makes the putting position of antenna select more simultaneously.And, antenna utilizes antenna body jointly to radiate with earth plate, forms the radiation pattern of high directivity, thus avoids interfering with other aerial radiation.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, technical solutions of the utility model are clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As depicted in figs. 1 and 2, this utility model provides a kind of antenna 100, and it is mainly used in AP, Set Top Box wireless device.Described antenna 100 includes earth plate 110 and the antenna body 120 being made up of sheet metal integrated punching, described antenna body 120 is in an inverted L-shaped, it has a plate 121 and a radiant panel 122, and connecting plate 121 is vertically connected with earth plate 110, and radiant panel 122 is spaced and parallel with earth plate 110 relative.
Specifically, the big I of the earth plate 110 of antenna 100 designs according to resonant frequency, and the length of the connecting plate 121 of antenna body 120 can design according to antenna band Len req.More preferably, the sheet metal of antenna 100 is ironware.In actual design, according to different wireless device environment, to obtain required frequency and the antenna of impedance matching, antenna performance can be made by the geometry of antenna 100, radiant panel 122 are finely adjusted with the distance of earth plate 110 and the size etc. of earth plate 110 to reach optimization.
Refer to Fig. 1, for the embodiment 1 of this utility model antenna 100, wherein, the connecting plate 121 of antenna body 120 vertically bends extension and is formed from an outward flange of earth plate 110.
Refer to Fig. 2, embodiment 2 for this utility model antenna 100, wherein it is with the difference of embodiment 1: the middle part of described earth plate 110 offers a rectangular window 111, the connecting plate 121 of antenna body 120 vertically bends extension and is formed from an inward flange of the window 111 of earth plate 110, and the radiant panel 122 of antenna body 120 is relative with window 111.
Please continue to refer to Fig. 1 and Fig. 2, described antenna 100 has a welded plate 130 further, and welded plate 130 bends to extend towards earth plate 110 from the ending vertical of the radiant panel 122 of antenna body 120 and forms, and welded plate 130 is spaced and parallel with connecting plate 121 is oppositely arranged.Offering several spaced screw hole 112 on described earth plate 110 further, antenna 100 is removably assembled by earth plate 110 and is fixed on wireless device, and welded plate 130 is for welding with the wire rod of wireless device.More preferably, earth plate 110, connecting plate 121, radiant panel 122 and welded plate 130 are all rectangles.
