The applicant's Chinese patent 03267749.9 has disclosed frequency band in 800MHz～4000MHz, and voltage standing wave ratio is less than 1.5 Wide-frequency antenna on ceiling; But its radiant body is connected as a single entity by the inverted cone of the spherical crown on top and bottom and constitutes, the total height of radiant body is 40mm～70mm, it has solved the problems referred to above of most of Wide-frequency antenna on ceiling on the market, but it has two drawbacks: one is because spherical crown is arranged at radiant body top, total height is higher, need more material, make cost increase; It is difficult for to expand other function, as install the function of lamp additional in Wide-frequency antenna on ceiling two because radiant body seal.
[utility model content]
The utility model provides a kind of economical with materials to make cost reduce and can expand the low profile double-wideband omnidirectional ceiling mount antenna of other function at the above-mentioned defective of prior art.
In order to solve the problems of the technologies described above, the utility model comprises radiant body, base plate and radome, and the bottom of radiant body is fixed on the base plate, and radome is fixed on the base plate, and radiant body is an inverted cone, the upper circumferential edge of inverted cone stretch out one the circle flange ring.
The circular cone base angle of above-mentioned radiant body is 90 °～120 °, and the height of this radiant body is＜35mm.
The thickness of above-mentioned radiant body is 0.5mm～1.0mm.
Be provided with ground strip between above-mentioned flange ring and metal base plate.
Above-mentioned ground strip has three, is arranged on equably between flange ring and the metal base plate.
The thickness of above-mentioned ground strip is 0.5mm～1mm, and its width is 1mm～8mm.
Be provided with feeder pillar between above-mentioned radiant body bottom centre and the metal base plate center.
Above-mentioned radome is 30～70mm to the outside total height of metal base plate.
Above-mentioned low profile double-wideband omnidirectional ceiling mount antenna can be operated in 806MHz～960MHz and the 1710MHz～2500MHz frequency band simultaneously, its voltage standing wave ratio＜1.5.
The utility model is with respect to the beneficial effect of prior art: because radiant body top does not have spherical crown, total height has also reduced, and causes cost to reduce thereby material is reduced; And can in the radiant body that opens wide, other object be set, as lamp, make this low profile double-wideband omnidirectional ceiling mount antenna can expand other function.Therefore by adopting said structure and mode, just can provide a kind of economical with materials to make cost reduce and can expand the low profile double-wideband omnidirectional ceiling mount antenna of other function.
