Description
[technical field]
The present invention relates to mobile communication antenna field, be specifically related to a kind of broadband dual polarized antenna and radiating element thereof.
[background technology]
Along with the development of mobile communication cause, bandwidth and performance to antenna for base station are had higher requirement.
Building up and runing along with 3 G mobile communication network, and WLAN, the broadband wireless network extensive uses such as WiMax, market has proposed huge demand to broad-band antenna, particularly can cover the broad-band antenna of the 1.7GHz 2.7GHz frequency range of following communication standard: GSM1800, DCSCDMA 1900, IMT-2000, TD-CDMA, WLAN, WiMax etc.
Along with application and the fast development of wireless technology, electromagnetic environment is day by day complicated, has proposed more and more higher requirement to the design of mobile communication Bipolarization antenna for base station.The electric property of antenna requires high-isolation, high-gain, main shaft cross polarization discrimination requires to be greater than 15dB, ± 60 ° of cross polarization discriminations require to be greater than 10dB, require to have good directivity and wave beam convergence simultaneously, and very low third order intermodulation index.
Enterprise, in fierce market competition, is not only required to provide the broadband base station antenna of function admirable, but also is required to reduce the production cost of antenna as far as possible.This just must claim to the technological layer of antenna, requires that designed antenna structure is simple firmly, volume is little, lightweight, it is simple and easy, easy for installation to process, it is simple, with low cost to weld, is applicable to producing in enormous quantities.
At present, in the solution of broad-band antenna, meet the above antenna requiring little simultaneously.General symmetrical dipole radiating element is in actual applications for Bandwidth, with the oscillator arms Width of polarization orthogonal on can amplify, meanwhile, for weight reduction and save Material Cost, can only retain again the largest contours size of oscillator arms.Refer to several the known solution that those skilled in the art propose below:
Please refer to the shape of the oscillator arms that No. 4184163 patent announcements of US disclose, its oscillator arms adopt circle shape structure and be finally reduced in Principle of Antenna and electric property on suitable circular ring structures all; Also can be with reference to No. 4510501 patent announcements of US, oscillator arms wherein adopt square structure and be finally reduced in Principle of Antenna and electric property on suitable square ring structures (be tending towards Q-RING when corner cut is cut very littlely, corner cut can be tending towards triangle ring or other polygon ring while cutting very greatly) all.The oscillator arms end of these two patents is all directly closed connection above, fails to make full use of near the free space of oscillator arms, makes oscillator arms size still bigger than normal.Above two patents, except oscillator arms size is large, its barron structure is also not suitable for the feed that is coupled, and limited bandwidth has limited its range of application.
Further refer to No. 6933906 patent announcements of US, its oscillator arms adopting is square structure, Ba Lun adopts sealing column construction, be beneficial to and realize coupling feed and broadband character, but sealing Ba Lun inwall is difficult for guaranteeing electroplating quality, therefore the intermodulation characteristic of radiating element is also difficult to obtain assurance, and isolation characteristic between the different polarization of oscillator is poor; CN 101707291A public announcement of a patent application a kind of broadband radiating unit, the larger-size problem of its same unresolved oscillator arms, though its Ba Lun adopts the hollow square column structure of sealing in addition, still cannot reach the technique effect of the intermodulation characteristic of guaranteeing radiating element.
From above-mentioned analysis, in prior art, for broadband dual polarized antenna, between the size of its radiating doublet adopting and electric property, there is certain contradiction.
[summary of the invention]
The present invention is exactly in order to solve aforementioned contradiction, a kind of broadband dual polarized antenna radiating element of simple in structure, easily manufactured, with low cost, function admirable is provided, keeping under the set prerequisite of the electric property of radiating element the size of further dwindling radiating element.
Further, the present invention adapts to the proposition of aforementioned radiating element, and a kind of broadband dual polarized antenna is provided, to make this radiating element more practical.
