Abstract
The utility model discloses a dual-band ultra-wideband omni-directional antenna, comprising a metal reflection plate, a radiator and a metal sheet. The radiator is arranged above the metal reflectionand comprises a first radiator and a second radiator. The bottom surface of the first radiator takes the conical surface. The second radiator is arranged inside the first radiator, and the upper end surface of the second radiator is higher than that of the first radiator. The metal sheet is arranged at the top part of the second radiator and covers the top part of the second radiator. As both thefirst radiator and the second radiator are the symmetrical structures, and the top end of the second radiator is provided with the metal sheet, omni-directional communication can be realized, and thebandwidth is within 806 to 960MHz and within 1,710 to 2,500MHz.

Moreover existing communication antenna is not considered and the harmony of surrounding environment owing to only pay attention to the electrical quantity and the communication function of antenna, therefore influences natural landscape and urban look, difficult base station construction and the demand for development of adapting to.
Summary of the invention
The purpose of this utility model provides a kind of double frequency ultra wideband omni-directional antenna, and the bandwidth of this antenna is 806MHz～960MHz and 1710MHz～2500MHz, and can comprehensive communication.
The utility model to achieve the above object, the technical scheme of being taked is:
Provide a kind of double frequency ultra wideband omni-directional antenna to comprise metallic reflection plate, radiant body and sheet metal.The central axes of the central axis of radiant body and metallic reflection plate, radiant body place the top of metallic reflection plate, and radiant body comprises first radiant body and second radiant body; The bottom surface of first radiant body is a taper seat; Second radiant body is arranged at the first radiant body inside, and the upper surface of second radiant body is higher than the upper surface of first radiant body.Described sheet metal is fixed in the top of second radiant body and covers the second radiant body top.
The beneficial effects of the utility model
Because the dead in line of first radiant body, second radiant body and the metallic reflection plate of the utility model radiant body, be symmetrical structure, and the sheet metal that is provided with of the second radiant body top, therefore, can not only comprehensively communicate by letter, bandwidth is 806MHz～960MHz and 1710MHz～2500MHz.

Embodiment
Further specify the architectural feature of the utility model double frequency ultra wideband omni-directional antenna below in conjunction with accompanying drawing.
See also Fig. 1 and Fig. 2, Fig. 1 and Fig. 2 are first embodiment of the present utility model, and in first embodiment, double frequency ultra wideband omni-directional antenna comprises metallic reflection plate 1, radiant body 2, sheet metal 3.
Metallic reflection plate 1 is disc in the present embodiment, and certainly, metallic reflection plate 1 also can be any shape in square, triangle, the polygon.
First radiant body 21 is that the bottom surface is the cylinder of taper seat, and the circular cone bottom surface of first radiant body 21 and the distance of metallic reflection plate 1 are greater than the distance of conical tip and metallic reflection plate 1.
Second radiant body 22 is arranged in first radiant body 21, and the upper surface 221 of second radiant body 22 is higher than the upper surface 211 of first radiant body 21.The dead in line of second radiant body 22, first radiant body 21 and metallic reflection plate 1 also.The bottom of second radiant body 22 contacts with the circular cone bottom surface of first radiant body 21.Second radiant body 22 is a metallic cylinder, and the cylinder of second radiant body 22 and first radiant body 21 also can be made of the number of metal bar.
Under the situation of size restrictions short-circuit piece 4 need be set in order to reach the requirement that bandwidth is 806MHz～960MHz and 1710MHz～2500MHz and to be subjected in entire antenna.Short-circuit piece 4 one ends are connected in metallic reflection plate 1, and an other end is connected in radiant body 2.Short-circuit piece 4 can be one, also can be many.In the present embodiment, short-circuit piece 4 is two and the symmetrical both sides that are distributed in first radiant body 21.
See also Fig. 3 and Fig. 4, Fig. 3 and Fig. 4 are second embodiment of the present utility model, and similar elements adopts same label among this embodiment and first embodiment.The difference of this embodiment and first embodiment is: the top of first radiant body 21 is provided with Extendible flake 5.Extendible flake 5 is in order to the standing wave of tuned antenna.Extendible flake 5 can be a slice, two, four and five.The upper end of Extendible flake 5 is lower than the upper surface 221 of second radiant body 22.
The utility model and antenna cover are used so that entire antenna is fixed on the building.Antenna cover comprises stay pipe, and first radiant body 21, second radiant body 22 and the metallic reflection plate 1 of described omnidirectional antenna are fixed in the antenna cover, and after cable passed stay pipe and metallic reflection plate 1 through hole, the core skin of cable was fixed on the metallic reflection plate 1.The heart yearn of cable contacts with first radiant body 21, thereby entire antenna is carried out feed at the bottom and the cable of first radiant body 21.
