Abstract
The utility model discloses a top attaching type mobile communication antenna, which consists of an antenna outer cover, a metallic mounting bottom board and a radiating body part arranged between the antenna outer cover and the metallic mounting bottom board. Wherein, the antenna outer cover takes a revolving symmetrical cap shape. The utility model is characterized in that the internal lateral on the lower edge of the antenna outer cover is firmly buckled with the metallic mounting bottom board. The internal part of the antenna outer cover is provided with a plurality of fixing and supporting radiating bodies and supporting pillar arranged on the bottom board. The radiating body part consists of an upwardly arranged radiating vibration generator and a downwardly arranged reflecting disc as well as a metallic conductor connected with the radiating vibration generator and the reflecting disc. The bottom of the radiating vibration generator is connected with a feed line core. The top part of the reflecting disc is connected with a feed line shielding layer. The radiating vibration generator is connected with the reflecting disc through an insulating flue. The radiating vibration generator takes a structure of a hoper shaped metallic body and the reflecting disc takes a structure of flat top conic body with a flange. The top attaching type mobile communication antenna has the advantages of smart and decent appearance, convenient installation and application as well as excellent effect.
Description
Technical field
The utility model relates to a kind of small-sized mobile communication antenna, specifically relates to the small-sized mobile communication antenna of ceiling type.
Background technology
For mobile communication, increase coverage and be improve communication quality and efficient important measures, but in the area of coverage, still there is blind area and the signal place that is beyond one's reach, as office building, tunnel, market place builet below the ground, underground parking lot etc., so people have adopted the form of indoor overlay communication system to solve these problems.Wherein the ceiling type antenna is a kind of of currently used indoor cover antenna, the ceiling type antenna of prior art generally by antenna cover, base plate is installed and is located at antenna cover and constitute with the radiant body of installing in the base plate, link together by screw and screw hole column between antenna cover and the installation base plate, the gap is bigger between antenna and the outer cover, whole ceiling type antenna volume is relatively large, its installation simultaneously is not too convenient, and cost is also higher, and radiation effect remains further to be improved.
Summary of the invention
The ceiling type mobile communication antenna that provides a kind of profile small and exquisite, attractive in appearance and easy to install, effective is provided the purpose of this utility model.
In order to achieve the above object, the utility model has adopted following technical scheme: this ceiling type mobile communication antenna by antenna cover, base plate is installed and is located at antenna cover and the radiant body installed between the base plate partly constitutes, antenna cover is rotational symmetric cap shape shape, the lower edge of antenna cover is inboard firmly to snap together with base plate is installed, and is provided with the support column of plurality of fixed and supporting antenna and base plate in antenna cover.
The lower edge of described antenna cover is provided with interior side flanging, base plate is installed is fastened in the flange; Also can adopt in the lower edge inboard of antenna cover boss is set, base plate is installed is fastened in the boss;
Described aerial radiation body portion is made of radiating doublet that is located at top and the reflecting disc that is located at the bottom, is connected to metallic conductor between radiating doublet and reflecting disc, and the radiating doublet bottom is connected with cable, links together by insulating cement between radiating doublet and reflecting disc.This radiating doublet is the funnel-form metallic object.
Described antenna cover middle part also is provided with annular concave platform.
Adopt the beneficial effect of said structure to be, since antenna cover of the present utility model with install that the mode by fastening is connected between the base plate, thereby make the utility model compared with prior art, easy to install, because fastening structure need not double-screw bolt is set in outer cover, the height of outer cover can be reduced relatively simultaneously, monnolithic case also reduces relatively, make the utility model outer cover and inhale top transition sleekly, and also be provided with annular concave platform in the middle part of the antenna cover, make the utility model profile more attractive in appearance; Antenna part of the present utility model is made of radiating doublet and reflecting disc, and by radiation and the effective dead zone-eliminating of radiation reflected energy, result of use is better.
The drawing explanation
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the antenna cover of the utility model Fig. 1 and the local enlarged diagram of fastening structure that metal is installed base plate.
Embodiment
As shown in Figure 1, ceiling type mobile communication antenna of the present utility model by antenna cover 1, base plate 6 is installed and be located at antenna cover 1 with installation base plate 6 between radiant body partly constitute, antenna cover 1 is rotational symmetric cap shape shape, its middle part also is provided with annular concave platform 1-1, the lower edge of antenna cover 1 is inboard firmly to snap together with installation base plate 6, it is that upper end-face edge in antenna cover 6 is provided with interior side flanging, base plate 6 is installed is fastened in the flange; Also can adopt in the lower edge inboard of antenna cover 1 boss is set, base plate 6 is installed multiple snap-fit attachment such as is fastened in the boss, as shown in Figure 2; Antenna part is made of the radiating doublet 2 that is located at top and the reflecting disc 5 that is located at the bottom and the metallic conductor 3 that is connected radiating doublet 2 and reflecting disc 5, radiating doublet 2 bottoms are connected with the feeder line core of cable 7, reflecting disc 5 tops are connected with the feeder shield layer, and 5 of radiating doublet 2 and reflecting discs link together by insulating cement 4; This radiating doublet 1 is the funnel-form metallic object in the present embodiment, and reflecting disc is a flanged pin flat-top cone.In antenna cover 1, also be provided with the support column 1-2 of plurality of fixed and supporting antenna and base plate 6; Support column 1-2 by being pressed on the base plate 6, will installing reflecting disc 5 base plate 6 simultaneously and inhale on the top by being pressed in.
