A kind of omnidirectional antenna
[technical field]
The utility model relates to a kind of antenna, is specifically related to a kind of omnidirectional antenna, belongs to the antenna product technical field.
[background technology]
Existing antenna product such as conical antenna, monopole antenna etc., mostly design at specific frequency range, and most of directional antenna exists certain signal blind zone.Simultaneously, existing antenna structure complexity, bulky, design is loaded down with trivial details, versatility is relatively poor.Along with development of Communication Technique, particularly to popularize such as a large amount of of the 3G communication technology, these antennas are difficult to meet the demands.
Therefore, for avoiding the problems referred to above, the necessary omnidirectional antenna that a kind of novel structure is provided is to overcome described defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of this utility model is to provide a kind of omnidirectional antenna of simple in structure, bandwidth.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of omnidirectional antenna, and it comprises base, connector, first Department of Radiation, second Department of Radiation and coaxial cable, wherein, described first Department of Radiation and second Department of Radiation are positioned at the base top; Described connector one end connects first Department of Radiation, and the other end connects coaxial cable; The central axes of described first Department of Radiation and second Department of Radiation.
Preferably, described first Department of Radiation is conical structure.
Preferably, the cylindrical structure of described second Department of Radiation.
Compared with prior art, the utlity model has following beneficial effect: omnidirectional antenna of the present utility model is by being provided with conical first Department of Radiation and columniform second Department of Radiation, thereby makes this omnidirectional antenna can comprehensive communication.And plurality of advantages such as that omnidirectional antenna of the present utility model also has is simple in structure, bandwidth.
[description of drawings]
Fig. 1 is the structural representation of omnidirectional antenna of the present utility model.
[embodiment]
See also shown in the Figure of description 1, the utility model is a kind of omnidirectional antenna, and it comprises base 1, connector 2, first Department of Radiation 3, second Department of Radiation 4 and coaxial cable 5.
Wherein, described base 1 is the disc-shaped structure setting.Described first Department of Radiation 3 and second Department of Radiation 4 are positioned at base 1 top, and this first Department of Radiation 3 and second Department of Radiation 4 are integrally formed, thus convenient the manufacturing.Further, described first Department of Radiation 3 is conical structure; And second Department of Radiation, 4 cylindrical structures, it is positioned at the top of first Department of Radiation 3.Described connector 2 one ends connect first Department of Radiation 3, and the other end connects coaxial cable 5.And the central axes of described first Department of Radiation 3 and second Department of Radiation 4.
Above embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within made any modification, be equal to replacement, improvement etc., all should be included within the protection range of this creation.
